E <br />C. Overlap connections may be used on latitudinal (i.e. butt) seams if the <br />GEOSYNTHETICS CONTRACTOR provides the DESIGN ENGINEER <br />independent test documentation which demonstrates that the load/deformation <br />characteristics of the overlap of geogrid materials is equal to or exceeds those of the <br />geogrid. The minimum overlap shall be 3 feet. <br />3.4 FILL PLACEMENT OVER GEOGRID <br />A. Backfill material shall be placed in lifts and compacted as directed under Section <br />02300. Backfill shall be placed, spread, and compacted in such a manner that <br />minimizes the development of wrinkles in and/or movement of the geogrid. <br />B. Tracked construction equipment shall not be operated directly on the geogrid. A <br />minimum fill thickness of 6 inches is required prior to operation of tracked vehicles <br />over the geogrid. Turning of tracked vehicles should be kept to a minimum to prevent <br />tracks from displacing the fill and damaging the geogrid. <br />3.7 REPAIR <br />A. Any geogrid damaged during installation shall be replaced by the either the <br />EARTHWORK CONTRACTOR or GEOSYNTHETICS CONTRACTOR, <br />depending on the party that caused the damage, at no additional cost to the Owner. <br />B. Coated geogrids shall not be used if the coating is torn, shedding, cracked, punctured, <br />flawed or cut, unless a repair procedure is carried out as approved by the Design <br />Engineer. The repair procedure shall include placing a suitable patch over the <br />defective area or applying a coating solution identical to the original coating. <br />3.8 PROTECTION <br />A. Follow the Manufacturer's recommendations regarding protection from exposure to <br />sunlight. <br />PART 4 MEASUREMENT AND PAYMENT (Refer to Section 01200, MEASUREMENT <br />AND PAYMENT PROCEDURES) <br />END OF SECTION <br />Forward Landfill WMU FU -13 <br />02779 7 <br />
