0 • Tensile Strength at 5 percent strain per ASTM D6637, Method A The QA/QC Consultant shall perform a tensile strength test. In addition to the ultimate tensile strength and the tensile strength at 5 percent strain, the entire load -strain curve shall be reported. Sampling Procedures. Samples will be taken across the entire width of the roll. Unless otherwise specified, samples will be 3 ft (1 m) long by the roll width. The QA/QC Consultant will mark the machine direction on the samples with an arrow. Test Results. The QA/QC Consultant will examine all results from laboratory acceptance testing and will report any nonconformance to the Construction Manager. Acceptance Test Failure. If a geogrid acceptance sample does not comply with the minimum requirements of the Specifications, the geogrid roll from which the sample was taken will be failed by the QA/QC Consultant, and replaced by the geogrid Manufacturer at no additional cost to the Owner. The Design Engineer shall be contacted to determine additional acceptance testing requirements. Adlk 4.6.3 Geogrid Installation qW Surface Preparation. Before geogrid installation, the QA/QC Inspector will: • Verify that all lines and grades have been verified by the Earthwork Contractor. • Verify that the underlying earthwork has been prepared in accordance with the specifications, and that all associated documentation has been completed. • Verify that soil surfaces do not contain protrusions that could damage the geogrid. • All construction stakes have been removed. • Verify that all aspects of surface preparation have been performed according to the specifications. Geogrid Placement and Seaming. During geocomposite placement the QA/QC Inspector will: • Observe the geogrid as it is deployed and record all defects and defect corrective actions (panel rejected, patch installed, etc.).
