ETj HUESKER inc <br />MKMHKH or <br />GEOSYNTHETIC <br />RESEARCH <br />INSTITUTE <br />•• ■ M <br />Fill Placement <br />The reinforced fill should be placed as shown in the constnicuon plans in 6-8 inch lifts <br />and compacted to a minimum 98% of Standard Proctor Density (ASTM D-698). <br />Backfill shall be placed, spread, and compacted in such a manner that eliminates the <br />devel pment of wrinkles and/or movement of the geogrid. Tracked construction <br />equipment should not be allowed to operate direcUy on the geogrid. A 6" minimum <br />thickness of backfill is required prior to operation of tracked vehicles over the geognd <br />Rubber-tired equipment may pass over the geogrid reinforcement at slow spee^ less than <br />6 mph. Sudden breaking and sharp turning should be avoided. Although the PVC <br />coating should protect the geogrid from UV exposure indefinitely. Huesker recommends <br />that the soU cover should be placed over the geogrid within 14 days as an extra <br />precaution. Only hand-operated compacUon equipment should be allowed within 3 feet <br />of wall face. <br />Drainage placement shall be placed in accordance with the constmction plans or ^ <br />modified by the wall design engineer. This may consist of a drainage collector pipe m <br />combination with a drainage ne^t in order to mamtain gravity flow to the outside of the <br />reinforced soil zone. <br />11107A SoulhCotnmefce Blvd .PO 0O< 41l529 .Charlotte.
