may not be advisable to scarify the top 8 inches prior to compaction.

If the CONTRACTOR deems it advisable not to scarify existing

natural ground, then moisten the native soil and compact it as

specified in Sub-paragraph 3.03.C.2, titled “Compaction of Coarse

Fill.”

3.1 GENERAL

A. Dispensing, Metering, or Mixing Epoxy Adhesive Components: Use portable,

automatic metering and mixing device or machine capable of maintaining prescribed

mix ratio within deviation of 5 percent or less, by volume.

B. Dispense epoxy components through specially designed static mixing nozzle that

thoroughly mixes epoxy components and places mixed epoxy at base of predrilled

hole.

C. Mixing Nozzles: Disposable and manufactured in several sizes to accommodate

different size and depth of holes.

D. Where large meter and mixing pumps are impractical, provide epoxy adhesive

packaged as follows:

1. Disposable, self-contained cartridges system capable of dispensing both

epoxy components in the proper mixing ratio, and fit into a manually or

pneumatically operated caulking gun.

2. Dispense components through a mixing nozzle that thoroughly mixes

components.

3.2 TESTING OF AUTOMATIC METERING AND MIXING PUMP SYSTEMS

A. Tests For Proper Ratio:

1. Retain small amount of dispensed adhesive for inspection after each time the

C. Ratio Check Procedure:

1. Disconnect dispensing head behind ON/OFF valve.

2. Place a 1 cup volume container and a 2 cup volume container under the

“B” and “A” component hose ends.

3. Actuate the pump until both cups are filled to proper proportion as

recommended by epoxy manufacturer.

3.3 HOLE SIZING AND INSTALLATION

A. Drilling Holes:

1. Electric or pneumatic rotary impact type with medium or light impact.

2. Drill Bits: Carbide-tipped in accordance with ANSI B212-15.

3. Hollow drills with flushing air systems are preferred. Air shall be free of oil,

water, or other contaminants which will reduce bond.

4. Where edge distances are less than 2 inches, use lighter impact equipment to

prevent microcracking and concrete spalling during drilling process.

C. Hole Diameter:

1. Reinforcing bar diameter or all thread rod diameter plus 1/8 inch.

D. Obstructions in Drill Path:

1. If the drill hits an existing reinforcing bar or other obstruction, stop drilling

and fill the hole with drypack mortar. Relocate the hole to miss the

obstruction and drill another hole. Repeat the above until the hole has been

drilled to the required depth.

2. Avoid drilling an excessive number of holes in an area which would

excessively weaken the structural member being drilled and endanger the

stabilityof the structure. When required, drypack holes which hit obstructions

and allow drypack to reach strength equal to the existing concrete being

drilled before drilling adjacent holes. Epoxy grout may be substituted for

drypack when acceptable to ENGINEER.

3. When existing reinforcing steel is encountered during drilling and when

acceptable to ENGINEER, enlarge the hole by 1/8 inch, core through the

existing reinforcing steel at the larger diameter, and resume drilling at

original hole diameter.

4. Bent Bar Dowels: Where edge distances are critical, and striking reinforcing

steel is likely, and if acceptable to ENGINEER, drill hole at 10 degree angle

or less from axis of reinforcing bar or all thread rod being installed.

E. Install reinforcing bars and all thread rods to depth, spacings, and locations as

indicated on the Drawings.

F. Cleaning Holes:

1. Insert long air nozzle into hole and blow out loose dust. Use air which is free

of oil, water, or other contaminants which will reduce bond.

2. Use a stiff bristle brush to vigorously brush hole to dislodge compacted

drilling dust.

3. Repeat step 1.

4. Repeat above steps as required to remove drilling dust or other material

which will reduce bond. The hole shall be clean and dry.

G. Cleaning Reinforcing Bars and All Thread Rods:

1. Degrease and sandblast reinforcing bars or all thread rods over embedment

length to near-white metal in accordance with Steel Structures Painting

Council, SP-10 finish. The reinforcing bar or all thread rod shall be free of

oil, grease, paint, dirt, mill scale, rust, or other coatings that will reduce bond.

H. Filling Hole with Epoxy:

1. Fill the hole with epoxy before inserting the reinforcing bar or all thread rod.

Fill hole with epoxy starting from back of the hole. Fill hole without creating

air voids.

2. Fill the hole with sufficient epoxy so that excess epoxy is extruded out of the

hole when the reinforcing bar or all thread rod is inserted into the hole.
