All values represent minimum average roll values <br /> 2. The design transmissivity is the hydraulic transmissivity of the geocomposite measured using water at 68°F <br /> f3°F(20°C t1.5°C)with a hydraulic gradient of 0.5,under a compressive stress of 5,500 psf. For the test,the <br /> geocomposite shall be sandwiched between a layer of 60-mil HDPE geomembrane and soil. The minimum test <br /> duration shall be 24 hours and the report for the test results shall include measurements at intervals over the <br /> entire test duration. <br /> 3. Certified test results performed within the last two years on the same product are acceptable. <br /> FORWARD LANDFILL WMU FU-04 GEOCOMPOSITE <br /> 02774 6 DRAINAGE NET <br />
