• Wide Width Tensile Strength at 5 percent strain per ASTM D6637 <br /> The QA/QC Consultant shall perform a wide width tensile strength test. In addition to the ultimate <br /> tensile strength and the tensile strength at 5 percent strain, the entire load-strain curve shall be <br /> reported. The QA/QC Manager will review all acceptance test results and report any non- <br /> conformance to the Construction Manager and Contractor. <br /> Sampling Procedures. Samples will be taken across the entire width of the roll. Unless otherwise <br /> specified, samples will be 3 ft (1 m) long by the roll width. The QA/QC Consultant will mark the <br /> machine direction on the samples with an arrow. <br /> Test Results.The QA/QC Consultant will examine all results from laboratory acceptance testing and <br /> will report any nonconformance to the Construction Manager. <br /> Acceptance Test Failure. If a geogrid acceptance sample does not comply with the minimum <br /> requirements of the Specifications,the geogrid roll from which the sample was taken will be failed <br /> by the QA/QC Consultant, and replaced by the Manufacturer at no additional cost to the Owner. <br /> 4.6.2 Geogrid Installation <br /> Surface Preparation. Before geogrid installation, the QA/QC Inspector will: <br /> • Verify that all lines and grades have been verified by the Earthwork Contractor. <br /> • Verify that soil subgrade does not contain protrusions that could damage the geogrid. <br /> • Verify that there are no excessively soft areas that could damage the geogrid. <br /> • All construction stakes have been removed. <br /> • Verify that all aspects of surface preparation have been performed according to the <br /> specifications. <br /> Geogrid Placement and Seaming. During geogrid placement the QA/QC Inspector will: <br /> • Observe the geogrid as it is deployed and record all defects and defect corrective actions <br /> (panel rejected,etc.). Verify that corrective actions are performed in accordance with the <br /> specifications. <br /> • Verify that equipment used does not damage the geogrid by handling,equipment transit, <br /> leakage of hydrocarbons, or other means. <br /> Page 44 <br />
