Upper Northern Portion of WMU FU-08 September 2009 <br /> Forward Landfill Project No.021605.09 <br /> material was approved for installation. A copy of the log of geomembrane received <br /> has been included in Appendix C. The manufacturer's QC data have also been <br /> included in Appendix C. <br /> 4.2.2 Conformance Testing <br /> Select samples of the HDPE were cut from random rolls of the geomembrane at the <br /> manufacturing plant by the third party testing laboratory for conformance testing <br /> in accordance with the project specifications and CQA manual. Conformance testing <br /> included: <br /> • density (ASTM D-1505) <br /> • carbon black content (ASTM D-1603) <br /> • carbon black dispersion (ASTM -5596) <br /> • thickness (ASTM D-5994) <br /> • tensile properties (ASTM D-638) <br /> • asperity height (GRI GM-12) <br /> A total of two (2) 60-mil thick double-sided textured HDPE geomembrane samples <br /> were tested for conformance. Based on 84,722 ft2 of HDPE received, this testing <br /> frequency corresponds to one test per 42,350 ft2 which satisfies the requirement of <br /> one test per 100,000 ft2. Results of the conformance testing indicated that the <br /> materials met the requirements of the project specifications are included in <br /> Appendix C. <br /> Vector Engineering,Inc.• 143E Spring Hill Drive-Grass Valley,CA 95945•(530)272-2448 <br /> -9- <br />
