A. Base Course: Sandy gravel material from local sources commonly used for road base construction (recycled materials such as crushed concrete or crushed asphalt are NOT acceptable).

1. Conforming to the following sieve analysis and requirements: a. 100 percent passing sieve size 1 inch. b. 90-100 percent passing sieve size 3/4 inch. c. 70-80 percent passing sieve size 3/8 inch. d. 55-70 percent passing sieve size #4. e. 45-55 percent passing sieve size #10. f. 25-35 percent passing sieve size #40. g. 3-8 percent passing sieve size #200.

2. Material may be either "pit run" or "crusher run." Avoid using clay based crusher run/pit run. Crusher run material will generally require coarse, well-draining sand conforming to AASHTO M6 or ASTM C 33 to be added to mixture (20 to 30 percent by volume) to ensure long-term porosity.

3. Alternative materials such as crushed shell, limerock, or crushed lava may be



used for base course use, provided they are mixed with sharp sand (20 to 30 percent) to ensure long-term porosity, and are brought to proper compaction. Without added sand, crushed shell and limerock set up like concrete and become impervious.

4. Alternative size and/or composition of base course materials should be submitted to Invisible Structures, Inc. (Manufacturer) for approval.

B. Gravel Fill: Obtain clean, washed, fine decorative gravel, must be sharp and angular (not rounded) stone, granite hardness, to fill the 1" high rings and spaces between the rings, not to be overfilled more than 1/4”. Maximum Size of stone should be: 3/16” to 3/8” and uniform in size - not graded.

C. Anchors: Typical anchors shall be 8" long nails with "fender” type washers 5/16" id x 1.25" od, all galvanized metal or similar corrosion resistant coating. Supplied anchors may vary in size and type based on source and availability.

D. (Optional) Binder: Portland cement, polymer binders, or tree resin binders may be added for additional aggregate stabilization. Contact the manufacturer. ATTENTION: Binders will reduce porosity –and some will even eliminate porosity – in the Gravelpave2 system.

2.5 GRASSPAVE2 SYSTEM MATERIALS

3.5. GRAVELPAVE2 INSTALLATION

A. Install the Gravelpave2 units by placing units with rings facing up/fabric below, and using small male/female connectors provided along each edge to maintain proper spacing and interlock the units. Cutting can be performed with pruning shears and knife, or portable power saw. Units shall be anchored to the base course, using anchors described above, as required to secure units in place from movement by traffic, at an average rate of 6 pins per square meter (high speed, heavy vehicles, fast turning movement will require additional anchors). Tops of rings shall be flush with the surface of adjacent hard surfaced pavements.

B. Smooth the fabric overlaps from one roll or unit to the adjacent unit. Take care to make sure there are no gaps in the fabric exposing base course.

C. Install gravel into rings after the units are anchored by "backdumping" directly from a dump truck, or from buckets mounted on tractors, with a minimum depth of 6”, then exit the site by driving forward over rings already filled. Sharp turning of vehicles on bare rings must be avoided. The gravel is then spread laterally from the pile using power



brooms, blades, flat bottomed shovels and/or wide "asphalt rakes" to fill the rings. A stiff bristled broom should be used for final "finishing". The gravel should be "compacted", if necessary, by using a vibrating plate or small roller, with the finish grade no less than the top of rings and no more than 0.25" above top of rings.

D. (Optional) If a binder for fill stone is desired (due to traffic speed, concentrated water flow, or other reason), use one of the following methods: 1. Portland cement: Mixed dry at 10% by weight with fill stone,. Place into rings

after thoroughly wetting the base, then lightly mist the surface after fill and compaction. Then, cover with a water resistant tarp, or plastic sheeting material for a minimum period of 3 days, or until the mixture has bonded.

Tops of rings shall be between 6 mm to 13 mm (0.25" to 0.5") below the surface of adjacent hard-surface pavements.

B. Install sand in rings as they are laid in sections by "back-dumping" directly from a dump truck, or from buckets mounted on tractors, which then exit the site by driving over rings already filled with sand. The sand is then spread laterally from the pile using flat bottomed shovels and/or wide "asphalt rakes" to fill the rings. A stiff bristled broom should be used for final "finishing" of the sand. The sand must be "compacted" by using water from hose, irrigation heads, or rainfall, with the finish grade no less than the top of rings and no more than 6 mm (0.25") above top of rings.

3.7. INSTALLATION OF GRASS OVER GRASSPAVE2
