described in this Section. Test the continuity of the repair in <br /> accordance with this Section. <br /> iv. Size of Samples: minimum 12 inches wide by 44-inches-long <br /> with the seam centered lengthwise. Cut a 1-inch-wide strip <br /> from each end of the sample and test these for (shear and <br /> peel) in the field. Cut the remaining sample into three parts <br /> for distribution as follows: <br /> • One portion for the GEOSYNTHETICS <br /> CONTRACTOR: 12 inches by 12 inches for <br /> quality control testing. <br /> • One portion for QA/QC CONSULTANT: <br /> 12 inches by 18 inches for quality assurance <br /> testing. <br /> • One portion to the OWNER for archive storage: <br /> minimum 12 inches by 12 inches. <br /> C. Field Testing <br /> i. The GEOSYNTHETICS CONTRACTOR shall test the two, <br /> 1-inch-wide strips by tensiometer for peel and shear, <br /> respectively. <br /> ii. Both test strips must meet peel and shear requirements for <br /> welded seams specified in Paragraph 3.2, C.8. <br /> iii. If any field test sample fails, follow failed test procedures <br /> outlined in this Section. <br /> D. Laboratory Testing performed independently by Construction Quality Assurance <br /> (CQA)Laboratory and Installer. <br /> 1. Test "seam strength" and "peel adhesion" (ASTM D3083 and D413). Test <br /> 1-inch wide samples at strain rate of 2 inches per minute. <br /> 2. Minimum acceptable values to be obtained for these tests are specified in <br /> Article 3.2, C.8. <br /> 3. Test at least five specimens for each test method. Four of five specimens <br /> must meet minimum requirements. None of the peel specimens may peel <br /> 100 percent,or the entire sample will be considered as failing. <br /> 4. Select specimens alternately by test from the samples(i.e.,peel, shear,peel, <br /> shear...). <br /> 5. Provide test results no more than 24 hours after receiving samples. <br /> 6. For double wedge welded samples, test both sides in peel. <br /> E. Failed Weld Procedures. <br /> 1. Follow these procedures when there is a destructive test failure. Procedures <br /> apply when test failure is determined by the QA/QC CONSULTANT, the <br /> GEOSYNTHETICS CONTRACTOR,or by field tensiometer. Follow one of <br /> the following two options: <br /> a. First Option. <br /> • Reconstruct the seam between any two passing test <br /> locations. The GEOSYNTHETIC'S CONTRACTOR can <br /> not perform the repair by extrusion welding the flap. <br /> b. Second Option. <br /> • Trace the weld at least 10 feet minimum in both directions <br /> Forward Compost Facility Stormwater Improvements <br /> 02778 17 HDPE GEOMEMBRANE <br />
