vandalism, damage from the actions of man, weather, animals and other sources. <br />The Geotechnical CQA Monitors shall observe that the material is not stored <br />directly in the ground and that storage of the geocomposite provides protection <br />against damage pursuant to ASTM D4873. <br />6.1.2 GEOCOMPOSITE CONFORMANCE TESTING <br />6.1.2.1 Tests <br />Upon delivery of the geocomposite, the Geotechnical CQA Monitor shall ensure <br />that samples are obtained andforwardedto a GAI Certified Independent <br />Laboratory for testing of conformance with the design specifications. <br />Conformance sampling and testing will be conducted in accordance with the <br />Project Specifications. <br />Thickness (ASTM D1777) <br />• Mass per unit area (ASTM D3776) <br />Hydraulic Transmissivity (ASTM D4716) <br />• Carbon Black Content (ASTM D1603) <br />• Tensile strength (machine direction; ASTM D1682) <br />Where optional procedures are noted in the test method, the requirements of the <br />Specifications shall prevail. Updated or alternative'ASTM Test Methods maybe <br />used to determine the physical properties of the geocomposite materials at the <br />discretion of the Construction Manager. <br />The results of Conformance Testing: -will be documented -by the Geotechnical <br />CQA Officer. <br />6.1.2.2 Sampling Procedures <br />Samples shall be taken across the entire width of the roll and shall not include the <br />first three (3) feet. Unless otherwise specified, samples shall be three (3) tlang <br />by the roll width. The Geotechnical CQA Monitor shall mark the machine <br />direction on the samples with an arrow and the Manufacturer's roll identification <br />number. <br />Unless otherwise specified, samples shall be taken at a rate of one per lot or one <br />per 100,000 square feet, whichever results in the greater number of samples. <br />6.1.2.3 Test Results <br />The Geotechnical CQA Officer shall examine all results from the laboratory <br />conformance testing. All specimens tested shall pass. If any specimen fails, the <br />entire sample shall be considered as a failure and rejected. In this event, the <br />geocomposite material represented by the sample shall be considered <br />-14- <br />C\2001-048\FINAL COVER CQA.DOC\08/20/01 <br />Geologic Associates <br />
