7 <br />G. Using a cutting die cut four 1 -inch specimens spaced evenly along the length of the <br />weld. <br />H. Using a field tensiometer, test specimens for peel adhesion, and bonded seam <br />strength (ASTM D6392). Alternate the specimens peel, shear, peel, and shear. Test <br />both sides of a wedge weld for peel strength. Test at a separation rate of two inches <br />per minute. <br />1 I. A trial weld for textured 60 -mil thick geomembrane is considered passing when the <br />following results are achieved. <br />' Property Test Designation Required Test Results (1) (3) <br />Wedge Weld (2) and (3) ASTM D6392 <br />Peel Separation 10 percent maximum peel at 400 % <br />elongation <br />Shear Strength FTB at 400 % elongation <br />Extrusion Weld (3) ASTM D6392 <br />Peel Separation 10 percent maximum peel at 400 % <br />elongation <br />Shear Strength FTB at 400 % elongation <br />(1) 2 of 2 specimens must pass all criteria <br />(2) Both sides of the wedge weld shall be tested for peel properties. <br />(3) Acceptable break (failure) codes per ASTM D6392 are <br />Wedge weld= AD and AD-Brk <10% <br />Extrusion Weld = ADI, AD2 and AD-WLD (as long as strength is achieved) <br />J. Repeat the trial weld in its entirety when any trial weld specimen fails in either peel <br />or shear. <br />K. When repeated trial weld fails, do not use welding apparatus and welder until <br />' deficiencies or conditions are corrected and two consecutive successful trial welds <br />are achieved. <br />3.06 DEPLOYMENT <br />A. Repair damage to subgrade or other underlying materials prior to completing <br />deployment of geomembrane. <br />B. Give careful consideration to the timing and temperature during deployment. Focus <br />' on verifying that there is no bridging or stresses in the geomembrane and there are <br />no wrinkles in the geomembrane that will fold over when covered with soil. <br />SHAW ENVIRONMENTAL, INC. <br />San Joaquin County — Extension of Cap Corral Hollow Sanitary Landfill — CH_Closure Cap Ext Proj_Technical Specs 4-19-12 Revl.DocRev. 0, 04/05/2012 <br />LLDPE Geomembrane <br />1 02779-11 <br />
