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 Landfill WMU FU -14 HIGH DENSITY POLYETHYLENE <br />02778 19 (HDPE) GEOMEMBRANE <br />
