Samples shall be taken at the rate of one sample per lot or one per 100,000 sq. ft <br /> (9,300 sq. m), whichever is greater and tested for bentonite mass per unit area, peel <br /> strength and hydraulic conductivity. Direct Shear tests as described in Section 2.LA <br /> shall also be performed. <br /> D. The QA/QC CONSULTANT will increase the frequency of sampling in the event <br /> that test results are negative. This additional testing shall be performed at the <br /> expense of the GEOSYNTHETICS CONTRACTOR. <br /> E. Any materials that are not certified by the Manufacturer in accordance with this <br /> section, or that has a hydraulic conductivity greater than that specified in this <br /> Section shall be rejected and replaced, at no additional cost to the OWNER. <br /> 3.3 SURFACE PREPARATION <br /> A. The EARTHWORK `CONTRACTOR shall be responsible for preparing the <br /> supporting(subgrade) soil. <br /> B. The subgrade shall be prepared in accordance with Section 02300,EARTHWORK. <br /> C. The subgrade surface shall be proof-rolled to identify soft zones, and eliminate <br /> irregularities, ruts, and abrupt changes in grade. Any unacceptable areas shall be <br /> repaired 'by the EARTHWORK CONTRACTOR, at no additional cost to the <br /> OWNER. <br /> 3.4 ANCHORAGE SYSTEM <br /> A. The anchor trench shall be excavated by the EARTHWORK CONTRACTOR prior <br /> to geosynthetic clay liner placement,to the lines and grades shown on the drawings. <br /> B. No loose soil shall be allowed in the anchor trench beneath the geosynthetics. <br /> C. The geosynthetic clay liner shall be anchored with compacted general earthfill, as <br /> identified on the drawings. <br /> D. Care shall be taken when backfilling the trenches to prevent any damage to the <br /> geosynthetic clay liner. <br /> ® Forward Landfill WMU FU-13 7 GEOSYNTHETIC CLAY LINER(GCL) <br /> 02777 <br />
