9 ameo <br />destructive samples from the primary PSSA geomembrane panel seams at a frequency of <br />one destructive test sample per 463 lineal feet of fusion welded seams, and one per 181 <br />lineal feet of extrusion welded seams. The test frequencies exceeded project requirements. <br />Field destructive testing of seams consisted of testing ten 1-inch wide coupons, five of which <br />were tested for peel, and five of which were tested for shear. Lone Star tested the inside <br />and outside tracks of the fusion welds for peel. Lone Star performed all destructive tests <br />on-site using a field tensiometer, and AMEC observed and documented all tests. <br />The specified acceptance criteria for 100-mil textured LLDPE to 100-mil textured LLDPE <br />shear tests was that four of the five coupons tested must have an ultimate strength of at <br />least 130 pounds per pulling inch (ppi) prior to yield. The specified acceptance criteria for <br />peel tests was that four of the five coupons tested must have ultimate strength of at least <br />100 ppi and achieve a Film Tear Bond (FTB) upon breaking. All destructive fusion seam <br />and extrusion seam samples met specifications. <br />The specified acceptance criteria for 100-mil smooth LLDPE to 100-mil smooth LLDPE <br />shear test was that four of the five coupons tested must have an ultimate strength of at least <br />130 pounds per pulling inch (ppi) prior to yield. The specified acceptance criteria for peel <br />tests was that four of the five coupons tested must have ultimate strength of at least 110 ppi <br />and achieve a Film Tear Bond (FTB) upon breaking. All destructive fusion seam and <br />extrusion seam samples met specifications. <br />The summaries of destructive test results for fusion and extrusion seams for the secondary <br />geomembrane are presented in Appendix K-6, and the summaries of destructive test results <br />for fusion and extrusion seams for the primary geomembrane are presented in <br />Appendix L-6. Record Drawing No. 4 (secondary geomembrane) and Record Drawing <br />No. 5 (primary geomembrane) presented in Appendix A shows the destructive test sample <br />locations. <br />I? <br />U <br />AMEC Earth & Environmental, Inc. <br />2000 S.
