The subsurface conditions at the project site were explored by 5 piezocone penetrometer test (CPTu)soundings and 5 standard penetration test (SPT) soil borings performed to nominal depths ranging from40 to 125 feet below the existing ground surface or bridge deck surface. Two SPT soil borings were laterperformed on the north side of the bridge to a nominal depth of 50 feet below the existing groundsurface as part of an additional exploration.
The subsurface conditions encountered in the borings and soundings were composed of six generalstratigraphic layers. These layers include:
Very loose to firm clean, slightly silty, silty and clayey SAND with trace gravel Very soft to soft silty and sandy low and high plasticity CLAY with trace gravel and trace organics
and high plasticity organic CLAY Very loose to firm clean, slightly silty and silty SAND with trace to some gravel, trace clay, trace
organics and trace shell fragments Very soft to soft silty and sandy high plasticity and organic CLAY and very loose to loose clayey
SAND Very loose to firm clean, slightly silty and silty SAND with trace to some gravel, trace clay and
trace shell fragments Very stiff sandy high plasticity SILT and firm to dense silty SAND with trace shell fragments
The groundwater table was encountered in the overland test borings and soundings at a depth rangingfrom about 2 to 13 feet below the existing ground surface at the time of exploration. Water depth inMattox Creek was averaged about 10 feet in VDOT inspection reports. The tidal variation of the PotomacRiver at Colonial Beach is about 2 feet.
Driven prestressed precast concrete piles will be used to support the proposed bridge bents. A pile tipelevation of -80 feet is estimated to achieve the required nominal bearing resistance for 24 inch squareprestressed concrete piles at the overwater bents.
To resist the lateral movements associated with the integral abutment bridge, steel H-piles are expectedto be used for supporting the abutments. A pile tip elevation of -70 feet is estimated to achieve therequired nominal bearing resistance for HP 12x74 steel piles.
Estimated lateral pile response based on the application of provided axial and lateral loads and expectedhorizontal movements is addressed within.
Traditional soil supported widened embankments will be constructed for the southern bridge approach.The northern approach is planned to be partially excavated and reconstructed using lightweightaggregate fill to minimize subsurface settlement. Dewatering will be needed for much of the northembankment reconstruction. Cantilever steel sheet piles will be installed along the east and west sides ofthe north embankment and abandoned in place.
Undercutting and backfilling with aggregate will be required for improving the existing conditions at thebase and toe of new slopes to accommodate the embankment widening.
Laboratory CBR values on well compacted samples ranged from about 3 to 15. A design CBR value of 6 isrecommended for the existing subgrade at future pavement areas. A design pavement section isprovided.

Purpose of ExplorationThe purpose of this exploration was to collectgeotechnical data overwater and on land near theexisting Route 205 bridge over Mattox Creek foruse in the design of a replacement bridge.Geotechnical recommendations for design andconstruction of the project foundations,embankments and pavements are provided basedon analysis of the field and laboratory dataobtained.
Project InformationThe proposed project will replace the existingbridge on State Route 205 over Mattox Creek nearOak Grove in Westmoreland County, Virginia. Asite location map is shown in Figure 1 and Drawing1 in Appendix A.
The existing bridge is approximately 175 feet longwith 6 spans and carries 2 lanes of traffic over atidal creek. A marsh causeway extends for severalhundred feet on the northern side of the bridge.The existing bridge is founded on 12 inch diameterpiers with each bent consisting of 2 timber pilesand cribbing. The bridge foundations have beenrehabilitated in the past. We understand the newbridge will be located along the same alignment asthe existing bridge and it will have approximatelythe same length and grades as the existing bridge.We understand there will be some widening toaccommodate current geometric standards whileminimizing environmental impacts and right-of-wayacquisition. Reconstruction of the roadwaypavements at the northern and southern ends ofthe bridge is expected.
The new bridge will have 2 overwater bents with 5piles each and 2 abutments with 8 piles each.Factored axial loads for the bridge bent piles weregiven as 243 tons for the Strength I load category.Factored axial loads for the abutment piles weregiven as 68 tons. Each substructure unit will besubject to lateral movements ranging fromapproximately 0.26 of an inch to 1.17 inches.
Grade increases along the roadway centerline willbe minimal at the southern approach. The northernapproach will receive centerline grade increasesranging from a few inches to approximately 2.5feet. Embankment slopes will be widened on bothsides of the roadway to accommodate the roadand bridge widening. Approximate depths of new
fill placed over the current embankment slopesrange from about 2 to 7 feet. New guard rails willbe installed in the widened top of slope.
Site DescriptionThe project site consists of the existing StateRoute 205, also known as James Monroe Highway,and the existing bridge over Mattox Creek. Theroadway and bridge are currently asphalt paved.Areas near the southern abutment consist ofsands, coastal vegetation, grasses and woodedareas while there is a marsh causeway along thenorthern abutment and approach. Surfaceelevations at the site range from about 0 to 10 feetbased on provided topographic data. The existingbridge deck elevation currently ranges from 9.45feet (msl) at the southern abutment (Abutment A)and 8.89 feet at the northern abutment (AbutmentB) based on provided profile drawings. The existingmudline elevation ranges from about 3 feet to-14.5 feet based on soundings taken in 2008included within a provided bridge inspection reportdated 2010.
Exploration ProgramThe subsurface exploration consisted of thefollowing sampling and testing program:

2 SPT soil borings to a nominal depth of 50 ftbelow existing grade at the northern approachperformed as part of an additional exploration.
2 pore pressure dissipation (PPD) testsperformed at representative cohesive stratadepths at selected CPT testing locations.
Seismic shear wave velocity testing wasconducted in one CPT sounding, near thesouthern abutment, at 1-meter intervals
1 shelby tube sample was taken at arepresentative cohesive strata depth at aselected SPT testing location.
4 bulk samples were collected at the on-landboring locations for laboratory CBR testing.
Additional laboratory testing included 20 naturalmoisture content tests, 10 classification tests, 6percent fines tests, 1 consolidation test and 1U-U triaxial strength test.
The testing locations and depths were selected byParsons Brinckerhoff and located in the field byGER. The approximate test locations are shown inFigure 2 and Drawing 2 in Appendix A. Field testresults are provided in Appendix B. Laboratoryresults are included in Appendix C. Exploration andsampling procedures are included in Appendix D.
Subsurface ConditionsThe subsurface conditions encountered at the CPTsounding and soil boring locations are shown onthe testing records in Appendix B.

strata on the testing records represent theapproximate interface location. In addition, thetransition between strata may be gradual. Waterlevels shown on the test records represent theconditions only at the time of the field exploration.
Standard penetration tests were conducted in theborings at discreet intervals in general accordancewith ASTM D 1586. Small disturbed samples wereobtained during the test and were used to classifythe soil. The resistances also provide a generalindication of soil strength and compressibility. Asummary of the penetration resistance profile isshown in Figure 3.
The soundings were conducted using an integratedelectronic seismic piezocone with a 15 cm2 tip anda 225 cm2 friction sleeve. The cone is designedwith an equal end area friction sleeve and a tip endarea ratio of 0.80. The piezocone dimensions andthe operating procedure were in accordance withASTM D 5778. Pore pressure filter elements madeof porous plastic were saturated under a vacuumusing silicone oil as the saturating fluid. The porepressure element was 6 mm thick and was locatedimmediately behind the tip (the u2 location). Tipresistance (qc), sleeve friction (fs) and dynamicpore pressure (u) data were recorded every fivecentimeters as the cone was advanced into theground.
Soil StratigraphySubsurface conditions encountered at the projectsite were composed of six general stratigraphiclayers. Figure 4 and Drawing 3 in Appendix Ashows an estimated subsurface profile at theproject site based on the interpreted conditionstaken from the boring and sounding logs.Variations between this estimated profile and theactual subsurface conditions can be expected.

GroundwaterThe groundwater table was encountered in theoverland borings and soundings at a depth rangingfrom about 2 to 13 ft below the ground surfaceduring the exploration. Fluctuations in thegroundwater level may occur due to variations intides, rainfall, evaporation, construction activity,surface runoff and other local factors.
Overwater Testing LocationsTesting locations 10BH-03, 10CP-02 and 10CP-03were located atop the existing bridge deck. Themeasured distance from the top of the existingbridge deck to the mudline ranged from about 20to 25 feet depending on testing location. Waterdepth in Mattox Creek was measured at about 10feet in VDOT inspection reports. The tidal variationof the Potomac River reported at Colonial Beach isabout 2 feet.
Surface MaterialsAsphalt paving measured between 12 and 18inches in depth at testing locations located withinthe existing roadway. Sandy upper layer soilswere present at testing locations located outside of
the existing roadway. Surface material thicknessand composition can be expected to vary acrossthe project site.
Subsurface EvaluationWe have evaluated the project information, siteand subsurface conditions described in thepreceding sections with regard to the proposedbridge replacement.
Prestressed precast concrete piles will be used tosupport the new bridge bents. The bent piles willbe comprised of five, 24 inch square prestressedconcrete piles. Eight, 12 inch square prestressedconcrete piles were originally considered forsupporting the abutments; however, the expectedlateral movements for the integral abutmentsresulted in excessive bending moment for 12 inchprestressed concrete piles.
Overwater piles for the new bridge bents shouldbear in the firm Stratum 6 sand layer. Assumingbearing resistance will be determined based ondynamic measurements and a resistance factor of0.65, the corresponding nominal bearing resistance(ultimate axial capacity) required for the 24 inchprestressed precast concrete piles is 385 tons. Atip elevation of at least -80 feet is estimated to berequired to achieve this resistance for the bent

piles. Estimated nominal bearing resistances for 24inch square prestressed precast concrete piles ofvarious lengths at overwater locations are providedin Figure 6 and Drawing 5 in Appendix A. Theseestimates assume that minimal scour belowcurrent mudline elevations in the creek will occur.Elevations have been taken from the provided siteprofile and shall be considered approximate.
Steel HP 12x74 piles will now be used forsupporting the abutments due to lateral loadingdemands. Abutment piles will potentially be subjectto downdrag forces due to settlement of the claylayer(s) as a result of fill and riprap placed aroundthe abutments. Abutment piles should also beinstalled into the firm Stratum 6 sand layers, andthe corresponding nominal bearing resistance(ultimate axial capacity) required for the abutmentpiles is 103 tons excluding drag forces. Estimatednominal bearing resistance along with unfactoreddrag loads for steel HP 12x74 piles of variouslengths are provided in Figure 7 and Drawing 6 inAppendix A. The corresponding nominal bearingresistance required for the abutment piles with afactored drag load allowance is estimated atapproximately 130 tons, which corresponds to a tipelevation of about -70 feet. The use of batter pilesshould generally be avoided at abutments or otherareas that may be susceptible to drag loading.
Lateral response of both overwater and abutmentpiles was examined using the provided axial andlateral loads for both overwater bents andabutments. Provided displacements from thermalchanges were also analyzed for each structurebased on a free head condition. Figure 8 andDrawing 10 in Appendix A shows the estimatedbending moment versus depth for 24 inchoverwater piles under the provided loads anddisplacements. Figure 9 and Drawings 11 and 12 inAppendix A show estimated bending momentversus depth for the steel H-piles at the abutmentsunder the provided loads and displacements.
The northern approach will receive centerlinegrade increases ranging from a few inches toapproximately 2.5 feet in the vicinity of Station21+00. Existing northern approach embankmentslopes on both sides of the roadway will beexpanded to various widths for the proposedimprovements, and we estimate the existing slopeswill receive grade increases up to approximately 7feet. We understand the northern approach hasexperienced significant settlement over the pastseveral decades.
To help mitigate settlement associated with thegrade increases, we originally considered atraditional improvement solution of stagedembankment construction with preloading to allowtime for consolidation to occur prior to finegrading. However, we understand there will be

environmental restrictions which significantly limitthe times of the year in which work adjacent towetlands can occur. As a result, VDOT requestedan alternative improvement solution for thenorthern approach consisting of a pile supportedembankment (PSE). We subsequently developed aPSE design for the northern approach that includeddriving concrete piles, excavating the existingembankment, constructing a geogrid reinforcedload transfer platform, and grading and paving instages. The PSE solution to mitigate settlement ofthe north approach had its own constructabilityand cost issues along with the request to installsheeting along the embankment periphery tofacilitate dewatering and to contain theconstruction. After further review, VDOT requestedan alternative solution using lightweight fill tominimize settlement from the grade increases.
We have re-evaluated the northern approach usinglightweight fill to reconstruct the embankmentsand widen the slopes. Of the various types oflightweight fill available, we have consideredlightweight aggregate fill consisting of ExpandedShale, Clay or Slate (ESCS) aggregate in the ¾” to#4 gradation range to be a technically andeconomically feasible material for the project. Thisaggregate material is constructed similar to that oftraditional earth fill material and has been used forsettlement mitigation purposes on numerous DOTprojects throughout the country. We havediscussed its use on this project with CarolinaStalite Company, an ESCS producer and distributorin the Mid-Atlantic region, who can supply anexpanded slate aggregate having a compacteddensity on the order of 60 pcf.
The objective of using lightweight fill is to minimizenet stress increases to the weaker subsurface soilsin order to minimize post-construction settlementsresulting from the roadway improvements. Thisstress reduction will require undercutting a portionof the existing earth embankment. We havecalculated embankment undercut depths toremove existing material weighing roughly thesame as the proposed improvements. Within theexisting roadway, this is expected to result in zeronet stress increase from the end of the bridge toapproximate Station 20+00. Stations further northrequire deeper undercutting due to having agreater final grade increase. We decided totruncate the embankment undercutting atelevation 1.0 due to groundwater and soft soilconsiderations. However, the net stress increases
within the existing roadway north of Station 20+00are still expected to be minimal. Stress increasesalong the new embankment slopes will result insome post-construction settlement, but roughlyhalf of the settlement that would occur withtraditional earth fill.

At the southern bridge approach, the proposedroadway grades are essentially the same as

existing grades along the roadway centerline.There are less wetland impacts associated with theroadway widening at this approach, but there areareas on the eastern and western sides of thesouthern abutment that will require gradeincreases up to approximately 7 feet. Weunderstand it is not desired to provide anyembankment improvements for settlementmitigation south of the bridge since the centerlinegrades are not increased and since it is notbelieved that the south side has experienced muchsettlement in the past.
The widened embankment slopes will extend intowetland areas over most of the project limits. Mostareas outside the roadway were not accessible toexploration as part of this project. Based on pastexperience and visual conditions, we expect it willbe necessary to undercut one or more feet ofexisting surface materials at the new slope baseand toe in order to improve toe support andprovide a more stable surface for slopeconstruction. Crushed stone underlain by geotextilefabric should be used for backfilling undercutexcavations at the toe on the southern approach.Lightweight aggregate fill may be used forbackfilling toe undercut excavations along thenorthern approach. It will likely be necessary toprovide more excavation in some places and mostof this excavation will encounter groundwater ortidal water. We have provided a detail for the basebid undercutting at the toe of slope, shown onDrawing 8 in Appendix A.
The Stratum 2 and Stratum 4 high plasticity andorganic clays encountered during the explorationwill be susceptible to long-term consolidationsettlement associated with the grade increases andwidened slopes. Along the existing embankmentslopes that will be widened, there will be addedembankment fill with grade increases ranging fromseveral inches to approximately 7 feet at both thenorth and south ends of the bridge. Calculatedprimary consolidation total settlements areestimated to be on the order of 2 inches undermaximum soil fill depths beneath the prisms ofnew fill. We expect total settlements beneathwidened slopes constructed with lightweight fill willbe slightly less.
Laboratory CBR values on well compacted samplestaken near the existing abutments ranged fromabout 3 to 15. A design CBR value of 6 isappropriate for the existing subgrade. A
preliminary pavement design section has beencalculated based on the future traffic data shownon the roadway plans.
RecommendationsThe following recommendations are providedbased on subsurface data obtained from the site,our engineering analysis of the subsurfaceconditions encountered, and the projectinformation furnished to us.
Deep Foundations Driven prestressed precast concrete piles for
supporting the bridge bents and steel H-pilesfor supporting the abutments should bearwithin the Stratum 6 sand layers.
A base bid tip elevation of -80 feet is estimatedto achieve the required nominal bearingresistance of 385 tons for the 24 inch squaredriven prestressed concrete piles for the bridgebents. Calculated resistance is shown onDrawing 5 in Appendix A. The estimatedresistances assume that minimal scour belowcurrent mudline elevations in the creek willoccur.
The nominal bearing resistance required for theHP 12x74 abutment piles along with a factoreddrag load allowance is estimated atapproximately 135 tons. This corresponds to atip elevation of about -70 feet. The unfactoreddrag load is estimated at approximately 20 tonsfor nominal 12 inch width pile sections.
Estimated lateral response (bending moment)of overwater and abutment pile sections underthe provided axial and lateral loads anddisplacements is shown on Drawings 10through 12 in Appendix A.
Piles should be spaced at least 3 pile diameterscenter-to-center. A group efficiency of 100% foraxial loads may be used at this spacing.Efficiency for laterally loaded pile groups istypically less than 100%. Load modificationfactors for lateral loading at the selected pilespacing should be in accordance with currentAASHTO specifications.
The axial resistances and estimated lateralresponses provided are based on piles drivenusing conventional impact driving methods. Useof jetting or spudding to facilitate pileinstallation may adversely affect axial and
Route 205 over Mattox Creek, Westmoreland County, VA October 11, 2013GER Project No. 110-5533 Page 8
GER
lateral pile resistance and these aids should beavoided or minimized to the extent possible.
Prior to installing production piles, a test pileprogram is recommended. As a minimum, oneoverwater test pile and one test pile at eachabutment should be driven. Test piles shouldgenerally be 5 feet longer than the estimatedpile lengths in case the desired bearing layer isdeeper than anticipated and to conductrestriking. Wave equation analysis for bearingand drivability should also be performed prior toand after the test pile installation.
Axial and lateral static load testing is the bestmeans for verifying individual pile capacity andmovement. The use of the pile driving analyzer(PDA) in place of traditional static load tests hassignificant economic benefits and has nowbecome commonplace. However, we havefound that dynamic testing tends tounderpredict ultimate resistance based on ourexperience in similar soil conditions.
We recommend that test pile capacities whichare evaluated by dynamic load testing beconducted using refined CAPWAP analysis withmeasurement data obtained during restrikeafter 7 or more days from the end of initialdriving. Input parameters should be selectedbased on extensive local experience with similarpiles in similar soil conditions and backcorrelation to results of static loading tests.
Installation of all piles should be monitored bythe Engineer for any indication of problems.Piles which fail to achieve the specified tipelevation or driving resistance may be subjectto rejection unless they are evaluated anddetermined to be acceptable by the Engineer.
Driven Pile Recommendations Piles should be driven to the specified tip
elevation with sufficient driving resistance toproduce the required safe bearing capacity.Acceptable driving resistance criteria is to bedetermined by the Engineer following the testpile program. Restriking piles at several daysafter initial driving may be required to verify soilsetup and strength gain.
Compatibility of the pile type and installationequipment is essential to produce a foundationthat performs satisfactorily. Installationequipment and methods used for the job pilesshould be the same or similar to that used for
the test pile program. Prior to installing piles,the contractor should submit a drivabilityanalysis and data sheets on the proposeddriving equipment and installation proceduresto the Engineer for evaluation.
The energy of the driving hammer should besufficient enough to install the piles into theStratum 6 sands without causing fatigue ordamage. For the 24 inch square concrete piles,we estimate a hammer energy in the range of140,000 to 240,000 ft-lbs will be required. Forthe steel HP piles, we estimate a hammerenergy in the range of 40,000 to 100,000 ft-lbswill be required. The ratio of the ram weight tothe pile weight should generally be in the rangeof 0.5 to 1. The preference for installing the 24inch piles is an air or hydraulic impact hammerwith a heavier ram weight to avoid overstressing the piles.
To the extent possible, pile installation shouldbe a continuous operation without terminationof driving until the point of acceptableresistance or embedment is achieved. If drivingis temporarily halted, the pile should beredriven to the required depth or to acombination of penetration and resistance thatis determined to be acceptable by the Engineer.
Lightweight Fill Embankment The base bid improvement section for the north
approach embankment consists of undercuttinga portion of the existing embankment, installinggeosynthetic layers, and constructing the newembankment using lightweight aggregate fill asshown on Drawings 7, 8 and 9 in Appendix A.
Lightweight aggregate fill should consist ofrotary kiln processed Expanded Shale, Clay orSlate (ESCS) aggregate material having aproven record of soundness and durability, andmeeting the following properties:
Gradation: ¾” to #4
Max. compacted wet density: 63 pcf
Min. compacted friction angle: 40 deg
Min. CBR value: 20
Soundness loss: <30%
Abrasion resistance: <40%
Chloride content: <100 ppm
pH value: 5 - 10
Route 205 over Mattox Creek, Westmoreland County, VA October 11, 2013GER Project No. 110-5533 Page 9
GER
Lightweight aggregate should be placed inuniform horizontal layers not exceeding 12inches in loose thickness. Constructionequipment other than for placement andcompaction shall not operate directly on thelightweight aggregate.
Each layer should be compacted using avibratory drum roller weighing no more than 12tons static weight. The minimum number ofroller passes is two and the maximum numberof passes is 6. Static rolling of the first layer(s)may be required at elevations close to thegroundwater table to minimize pumping of thesubgrade.
The compacted wet density of the lightweightaggregate should be determined using amodified version of AASHTO T99 that consistsof placing the aggregate in a standard 0.5 cubicfoot bucket in 3 equal layers and compactingeach layer using 25 blows of a 5.5 lb hammerdropped from 12 inches.
One layer of geotextile fabric should be placedon the prepared subgrade after excavation formaterial separation purposes. Geotextile shouldconform to Section 245 of the VDOT Road andBridge Specifications for subgrade stabilizationfabric.
One layer of triaxial geogrid should be placeddirectly over the geotextile fabric for basestabilization and to facilitate materialcompaction over soft subgrade. The stiffnessand rigidity of the geogrid are more importantthan its tensile strength. Recommendedminimum geogrid properties are as follows:
Aperture shape: triangular
Junction efficiency: 93%
Aperture stability: 3.6 kg-cm/deg
Radial stiffness @ 0.5%: 300 kN/m
The geogrid and geotextile should tie into thephasing sheet piles and perimeter sheet piles byupturning 12 inches minimum as shown onDrawing 8 in Appendix A. It is imperative thatthe geogrid and geotextile is pulled taught andfirmly secured to the subgrade and sheet pileedges during filling in order to develop thenecessary tension. Phasing sheet piles will becut off at the bottom of pavement grade andabandoned in place.
It may be necessary to confine and stabilizeslopes constructed with lightweight aggregatebeyond that of standard VDOT practice forearth slopes. Use of permanent turfreinforcement mats along with topsoil andvegetative cover should be considered.
The contractor should be prepared forextensive dewatering needs and excavating intosoft/wet material to accomplish the prescribedimprovements. Steel sheet piles installed alongthe periphery of the northern approach shouldbe used to assist in dewatering and earthworkefforts.
Steel Sheet Piles A row of cantilevered steel sheet piles will be
installed along each toe of slope along the newnorthern embankment and along themaintenance of traffic (MOT) phasing line. Thesheet piles will be designed and installed by thecontractor and abandoned in place.
Sheet piles installed along the toe of slope forthe northern approach should have a topelevation located above the normal high tidelevel. The tip of the sheet piles will reach theStratum 5 sand layer per VDOT instructions, sothe resulting length of sheeting is on the orderof 40 feet. The selected sheet pile sectionshould be sufficient enough to allow installationinto Stratum 5 without damage or misalignmentto the piles.
Sheet piles installed for the MOT phasing shouldhave a sufficient section and length to laterallysupport the retained material and surface loadsand to withstand installation through theexisting embankment into the subsurface soils.
Earthen Embankment Existing embankment slopes should be cleared
and stripped of all vegetation, topsoil and otherunsuitable materials. Embankment constructionmaterials, means and methods should follow allapplicable VDOT standards and specifications.
The embankment subgrade should becomposed of relatively firm suitable soils thatare free of debris, organic and loose material.This should be verified by a field inspector priorto constructing fill. If unsuitable subgradematerials are encountered, the Engineer shouldbe notified.
Route 205 over Mattox Creek, Westmoreland County, VA October 11, 2013GER Project No. 110-5533 Page 10
GER
Embankment slopes that will be widened intowetland and other soft soil areas will encounterunsuitable materials that require improvement.A base bid toe improvement at locations southof the bridge consists of undercutting 2 feetbeneath the base of the widened slope andbackfilling with VDOT #3 stone underlain bygeotextile fabric. Drawing 8 in Appendix Ashows a toe undercut and backfill detail.
Temporary work platforms over soft soils maybe required to construct the embankments.Work platform locations, depths and materialsshould be approved by the Engineer.
Excavated materials may be reused for theembankment widening provided that they meetthe criteria under Fill and Backfill. Some of theStratum 1 sandy soils are expected to meet thiscriteria. Existing suitable materials will likelyrequire drying to a suitable moisture contentprior to reuse. Highly plastic soils and thosecontaining excessive clay, organic, muck ordeleterious materials should not be used withinthe embankment cross section.
Fill materials, construction and compactionshould be monitored and approved by aqualified field inspector during construction.
At all times during construction, surfacedrainage should be managed to prevent wateraccumulation on the subgrade and erosion ofthe embankment slopes.
Earth embankment slopes should be protectedfrom erosion. Topsoil or mulch with vegetationunderlain by geosynthetic erosion control matsare believed to be the most cost effectiveerosion control alternative.
Fill and Backfill Representative samples of each proposed fill
material should be collected before fillingoperations begin and tested to determinemaximum dry density, optimum moisturecontent, natural moisture content, gradation,plasticity and CBR. These tests are needed forquality control during construction and todetermine if the fill material is acceptable.
Select material conforming to Type I, II or IIIby Section 207 of the VDOT Road and BridgeSpecifications should be used for grading andbackfilling in the structure and pavement areas.Compacted material in structure and pavement
areas should have a minimum CBR value of 20.Select material as above or suitable materialmeeting AASHTO M57 should be used for thesouthern approach embankment widening.
Fill and backfill soils should be spread in thin,even layers not exceeding 8 inches loosethickness prior to compaction. Each layer of soilshould be compacted to achieve no less than 95percent of the laboratory maximum dry densityas determined by VTM-1.
The moisture content of fill soils should bemaintained within ±3 percentage points of theoptimum moisture content determined from thelaboratory Proctor density test. Fills should befree of debris and deleterious materials andhave a maximum particle size diameter lessthan 2 inches.
The fill surface must be adequately maintainedduring construction. The fill surface should becompacted smooth and properly graded toimprove surface runoff while construction istemporarily halted. Excavations to receivebackfill should not be left open for extendedperiods.
Where backfill is required in excavations thatpenetrate the groundwater table, an initial 6 to12 in layer of #57 crushed stone should beused to serve as a stable base for compactionof subsequent lifts of fill. Groundwater shouldbe lowered below the crushed stone elevationby pumping prior to compacting the soil.
Fill should not be placed on wet or frozenground. Fill which becomes softened fromexcess moisture should be aerated andrecompacted to acceptable levels, removed andreplaced with new compacted fill, or asotherwise directed by the Engineer.
Lateral Earth Pressure Parameters The following general soil properties may be
assumed for typical local select fill materialwhen placed and compacted properly:

Retaining walls that are permitted to tilt at thetop may be designed for the active state lateralpressures. The minimum movement typicallyrequired for the active pressure condition isapproximately 0.005H for sand soils and 0.01Hfor clay soils, where H is the height of the wall.
Near corners and at other areas where the wallis restrained at the top and these minimummovements do not occur, walls should bedesigned for at-rest lateral pressures. Forsimplicity, equivalent fluid pressures may beused for design. The following pressures perfoot of wall height and per foot of wall lengthmay be used where relief of hydrostaticpressure is provided:

Pavements A design CBR value of 6 is appropriate for the
existing soils based on the laboratory CBR testresults. A preliminary pavement section for theproject based on the traffic data provided is:
2.0 in SM-12.5D Surface Course 2.0 in IM-19.0A Intermediate Course 4.0 in BM-25.0 Base Course 8.0 in Size 21B Untreated Aggregate Base
Pavement materials, design and constructionshould be in accordance with applicableprovisions of current VDOT standards andspecifications.
At all times during construction, positive surfacedrainage should be maintained to prevent wateraccumulation on the subgrade. Pavement andsubgrade deterioration often occurs fromconstruction traffic and placement of asphaltsurface courses should be delayed as long aspossible to allow any base and subgradecorrections to be made as a result from heavyequipment damage.
Pavement construction is best suited for thetraditionally drier summer and fall months tominimize deterioration of the subgrade soils.Use of geogrid or geotextile fabric products canbe incorporated into the design if warranted byconditions at the time of construction.
After completion of rough grading, the exposedsubgrades should be proofrolled to detect
pockets of soft or otherwise unsuitable material.Proofrolling should be conducted after asuitable period of dry weather to avoiddegrading an otherwise acceptable subgrade. Aloaded dump truck or other heavy rubber tiredconstruction equipment should be used forproofrolling.
Prior to paving, density testing and a secondproofroll should be performed on the aggregatebase material to determine if localized areashave degraded due to construction traffic ormoisture problems.

TEST BORING RECORDS
The enclosed test boring records represent our interpretation of the subsurface conditionsencountered at the specific boring locations at the time explorations were made based on visualexamination of the field samples obtained and selected laboratory classification testing ifperformed. The lines designating the interface between various strata on the boring recordsrepresent the approximate interface location. In addition, the transition between strata may bemore gradual than indicated. Water levels shown represent the conditions only at the time ofthe field exploration. It is possible that soil and groundwater conditions between the individualboring locations will be different from those indicated. Boring surface and strata elevations, ifshown, shall be considered approximate and are referenced to project datum shown on theplans or described in the geotechnical report unless noted otherwise.

Contractor: ConeTec, Inc.
Procedures: The CPT is a profiling tool described in ASTM D 5778 and various other publications.No physical soil sampling is conducted during the test. A compression modelelectronic piezocone penetrometer with a 15 cm2 tip and a 225 cm2 friction sleevewas used. The cone is designed with an equal end area friction sleeve and a tip endarea ratio of 0.8. Prior to testing, the cone internal force transducers were calibratedin a laboratory. At the beginning of each sounding, the cone was outfitted with avacuum-saturated, 6 mm thick porous plastic pore pressure element that is locatedimmediately behind the tip (the u2 location). The cone was advanced using a 15-tonhydraulic ramset mounted in a 25-ton truck or on a 20-ton tracked vehicle. As thecone was advanced into the ground, tip resistance (qc), sleeve friction (fs) anddynamic pore water pressure (u) were recorded every 2.5 centimeters(approximately every one inch).
Limitations: The enclosed testing records represent an interpretation of the subsurface conditionsencountered at the specific testing locations at the time explorations were made. It ispossible that subsurface conditions between testing locations will be different fromthose indicated. Strata contacts and surface elevations, if shown, shall be consideredapproximate and are referenced to project datum shown on the plans or described inthe geotechnical report unless noted otherwise.

GEOTECHNICAL EXPLORATION PROCEDURES
Boring, Sampling & Standard Penetration TestingStandard penetration testing and split barrel sampling are conducted at regular intervals in aborehole in accordance with ASTM D 1586. Standard practice on most GER projects is toperform this testing and sampling continuously within the upper 10 feet of the subsurface, andthen at maximum 5-foot center-to-center intervals thereafter. At the desired test depth, thedrilling tools are removed and a split barrel sampler is connected to the drilling rods andlowered back into the borehole. The sampler is first seated six inches into the bottom of thehole to penetrate any loose cuttings from the drilling operations. It is then driven an additional12 inches by the impact of a 140 pound hammer free-falling 30 inches. The number of hammerblows required to drive the sampler for each 6-inch interval is recorded. The combined numberof blows required to drive the sampler the final 12 inches is designated standard penetrationresistance or N-value. Representative portions of soil from each split barrel sample are placed inair tight glass jars or plastic bags and transported to a laboratory.
Undisturbed SamplingSplit barrel samples are used for visual examination and simple laboratory classification tests;however, they are disturbed and not sufficiently intact for quantitative laboratory testing suchas strength or consolidation. When such laboratory testing is desired, relatively undisturbedsamples are obtained by slowly pushing a 3-inch diameter, thin-walled (16 gauge) galvanizedsteel tube into the soil at desired sampling depths. This is followed by carefully removing thesoil-filled tube from the borehole and sealing the ends to prevent moisture loss. The procedureis described in ASTM D 1587. Undisturbed tube samples are most frequently used for samplingcohesive soils (clay and silt), but may be used to sample fine grained cohesionless soils with theaid of a piston sampling head.
ExcavationWhen explorations do not require machine-drilled borings, excavations, test pits, hand augerborings and other means described in ASTM D 4700 may be used to observe shallowsubsurface conditions and to collect soil samples. The maximum depth of these methods isgenerally limited by the depth of groundwater. These methods are useful in obtaining bulksamples for laboratory classification, compaction and other remolded tests.
Rock CoringCore drilling methods described in ASTM D 2113 are used to advance boreholes into rock orextremely dense soils which are not penetrable by conventional boring methods and typicallyexhibit more than 100 blows per foot by ASTM D 1586. Core drilling methods employed by GERuse double tube swivel-type designed equipment with a drilling fluid, in which an outer tuberotates and performs the cutting while the inner tube remains stationary and collects acontinuous sample of rock.
In-Situ MethodsIn-situ tests are sometimes used on projects to obtain additional subsurface data. Thesemethods provide direct and empirical measurement of various soil properties without collectionof actual samples. Because samples are not collected, it is not common practice in the U. S. to

utilize in-situ tests alone to accomplish geotechnical investigations. On projects where in-situtesting is used, it is customary to perform them in conjunction with borings.
Soil ClassificationSoil classification tests provide a general guide to the engineering properties of various soiltypes. Samples obtained during drilling operations are examined and visually classified by anengineer or geologist according to consistency, color and texture. These classificationdescriptions are included on the boring records. The classification system is primarily qualitativeand for detailed soil classification, two laboratory tests are necessary; grain size tests andplasticity tests. Using these test results, the soil can be classified according to the AASHTO orUnified Classification System (ASTM D 2487). Each of these classification systems and thein-place physical soil properties provides an index for estimating the soil's behavior. The soilclassification and physical properties obtained are presented on the following sheets.
Grain Size TestsGrain size tests are performed to determine the soil classification and the grain size distribution.The soil samples are prepared for testing according to ASTM D 421 (dry preparation) or ASTMD 2217 (wet preparation). The grain size distribution of soils coarser than the #200 U.S.Standard Sieve (0.074 mm opening) is determined by passing the samples through a standardset of nested sieves. Materials passing the No. 200 sieve are suspended in water and the grainsize distribution calculated from the measured settlement rate. These tests are conducted inaccordance with ASTM D 422.
Plasticity TestsPlasticity tests are performed to determine the soil classification and plasticity characteristics.The soil plasticity characteristics are defined by the Plastic Index (PI) and the Liquid Limit (LL).The PI is related to the volume changes which occur in confined soils beneath foundations. ThePI and LL are determined in accordance with ASTM D 4318.
Physical PropertiesThe in-place physical properties are described by the specific gravity, wet unit weight, moisturecontent, dry unit weight, void ratio and percent saturation of the soil. The specific gravity andmoisture content are determined by ASTM D 854 and D 2216, respectively. The wet unit weightis found by obtaining a known volume of soil and dividing the wet sample weight by the knownvolume. The dry unit weight, void ratio and percent saturation are calculated values.
California Bearing RatioThe California Bearing Ratio (CBR) test is a comparative measure of the shearing resistance of asoil. It is used with empirical curves to design asphalt pavement structures. The test isperformed in accordance with ASTM D 1883 or Virginia Test Method Designation VTM-8. Arepresentative bulk sample is compacted in a six-inch diameter CBR mold in five (5) equallayers, using 45 evenly spaced blows per layer with a 5.5 lb. hammer falling 12 inches. CBRtests may be run on the compacted samples in either soaked or unsoaked conditions, withsamples penetrated at the rate of .05 inches per minute to a depth of 0.5 inches. The CBRvalue is the percentage of the load it takes to penetrate the soil to a specified depth comparedto the load it takes to penetrate a standard crushed stone to the same depth.

Consolidation Tests Consolidation tests determine the change in height of a soil sample with increasing load. Theresults of these tests are used to estimate the settlement and time rate of settlement ofstructures constructed on similar soils. The test is run in accordance with ASTM D 2435 on asingle element of an extruded undisturbed sample. The test sample is trimmed into a diskapproximately 2½ inches in diameter and one inch thick. The disk is confined in a stainlesssteel ring and sandwiched between porous plates and subjected to incrementally increasingvertical loads, with the resulting deformations measured with micrometer dial gauges. Voidratios and percent strain deformation are then calculated from these readings. The test resultsare presented in the form of a stress-strain or vertical pressure versus void ratio curve.
Triaxial Shear TestsTriaxial shear tests are used to determine the strength characteristics and elastic properties of asoil sample. Triaxial shear tests are conducted either on relatively undisturbed samples of virginmaterial or on remolded-compacted samples of representative site materials. The samples arethen trimmed into cylinders and encased in rubber membranes. Each is then placed into acompression chamber and confined by hydrostatic cell pressure. An axial load is applied untilthe sample fails in shear. Test results are presented in the form of stress-strain curves andstress paths to failure.
Various types of triaxial tests may be performed. The most suitable type of triaxial test isdetermined by the loading conditions imposed on the soil in the field and by drainagecharacteristics of the site. Types of triaxial tests normally performed include:
Consolidated-Isotropic-Undrained (CIU test)Consolidated-Anisotropic-Undrained (CKoU test)Consolidated-Isotropic-Drained (CID test)Consolidated-Anisotropic-Drained (CKoD test)Unconsolidated-Undrained (UU test)

ConeTec Interpretations as of March 12, 2008 ConeTec’s interpretation routine provides a tabular output of geotechnical parameters based on current published CPT correlations and is subject to change to reflect the current state of practice. The interpreted values are not considered valid for all soil types. The interpretations are presented only as a guide for geotechnical use and should be carefully scrutinized for consideration in any geotechnical design. Reference to current literature is strongly recommended. ConeTec does not warranty the correctness or the applicability of any of the geotechnical parameters interpreted by the program and does not assume liability for any use of the results in any design or review. Representative hand calculations should be made for any parameter that is critical for design purposes. The end user of the interpreted output should also be fully aware of the techniques and the limitations of any method used in this program. The purpose of this document is to inform the user as to which methods were used and what the appropriate papers and/or publications are for further reference. The CPT interpretations are based on values of tip, sleeve friction and pore pressure averaged over a user specified interval (e.g. 0.20m). Note that qt is the tip resistance corrected for pore pressure effects and qc is the recorded tip resistance. Since all ConeTec cones have equal end area friction sleeves, pore pressure corrections to sleeve friction, fs, are not required. The tip correction is: qt = qc + (1-a) • u2
where: qt is the corrected tip resistance qc is the recorded tip resistance u2 is the recorded dynamic pore pressure behind the tip (u2 position) a is the Net Area Ratio for the cone (typically 0.80 for ConeTec cones)
The total stress calculations are based on soil unit weights that have been assigned to the Soil Behavior Type zones, from a user defined unit weight profile or by using a single value throughout the profile. Effective vertical overburden stresses are calculated based on a hydrostatic distribution of equilibrium pore pressures below the water table or from a user defined equilibrium pore pressure profile (this can be obtained from CPT dissipation tests). For over water projects the effects of the column of water have been taken into account as has the appropriate unit weight of water. How this is done depends on where the instruments were zeroed (i.e. on deck or at mud line). Details regarding the interpretation methods for all of the interpreted parameters are provided in Table 1. The appropriate references cited in Table 1 are listed in Table 2. Where methods are based on charts or techniques that are too complex to describe in this summary the user should refer to the cited material. The estimated Soil Behavior Types (normalized and non-normalized) are based on the charts developed by Robertson and Campanella shown in Figures 1 and 2. The Bq classification charts are not reproduced in this document but can be reviewed in Lunne, Robertson and Powell (1997) or Robertson (1990). Where the results of a calculation/interpretation are declared ‘invalid’ the value will be represented by the text strings “-9999” or “-9999.0”. In some cases the value 0 will be used. Invalid results will occur because of (and not limited to) one or a combination of:
1. Invalid or undefined CPT data (e.g. drilled out section or data gap).
2. Where the interpretation method is inappropriate, for example, drained parameters in an undrained material (and vice versa).
3. Where interpretation input values are beyond the range of the referenced charts or specified limitations of the interpretation method.
4. Where pre-requisite or intermediate interpretation calculations are invalid.

The parameters selected for output from the program are often specific to a particular project. As such, not all of the interpreted parameters listed in Table 1 may be included in the output files delivered with this report. The output files are provided in Microsoft Excel XLS format. The ConeTec software has several options for output depending on the number or types of interpreted parameters desired. Each output file will be named using the original COR file basename followed by a three or four letter indicator of the interpretation set selected (e.g. BSC, TBL, NLI or IFI) and possibly followed by an operator selected suffix identifying the characteristics of the particular interpretation run.

Young’s Modulus E
Young’s Modulus based on the work done in Italy. There are three types of sands considered in this technique. The user selects the appropriate type for the site from: a) OC Sands b) Aged NC Sands c) Recent NC Sands Each sand type has a family of curves that depend on mean normal stress. The program calculates mean normal stress and linearly interpolates between the two extremes provided in the Es/qt chart.
Mean normal stress is evaluated from: ( )3''''
