MEMBER OF <br /> HUESKER inc. GEOSYNTHETIC <br /> RESEARCH <br /> INSTITUTE <br /> Fill Placement <br /> The reinforced fill should be placed as shown in the construction 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 /> development of wrinkles and/or movement of the geogrid. Tracked construction <br /> equipment should not be allowed to operate directly on the geogrid. A 6" minimum <br /> thickness of backfill is required prior to operation of tracked vehicles over the geogrid. <br /> Rubber-tired equipment may pass over the geogrid reinforcement at slow speeds 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 soil cover should be placed over the geogrid within 14 days as an extra <br /> precaution. Only hand-operated compaction equipment should be allowed within 3 feet <br /> of wall face. <br /> Drainage placement shall be placed in accordance with the construction plans or as <br /> modified by the wall design engineer. This may consist of a drainage collector pipe in <br /> combination with a drainage net in order to maintain gravity flow to the outside of the <br /> reinforced soil zone. <br /> r <br /> 11107A South Commerce Blvd.•P.O.Box 411529•Charlotte,NC 28241 •Telephone(704)588-5500/(800)942-9418•Fax(704)588-5988 <br />
