TABLE 02774-1 <br />GEOCOMPOSITE PROPERTY VALUES <br />Notes: <br />1. All values represent minimum average roll values <br />2. The index transmissivity is the hydraulic transmissivity of the geocomposite measured using water at 68°F f3 °F <br />(20°C f 1.5°C) with a hydraulic gradient of 0. 1, under a compressive stress of 10,000 psf. For the test, the <br />geocomposite shall be sandwiched between stainless steel plates The minimum test duration shall be 15 <br />minutes. <br />3. The performance transmissivity is the hydraulic transmissivity of the geocomposite measured using water at <br />68°F t3°F (20°C ±1.50C) with a hydraulic gradient of 0.5, under a compressive stress of 10,000 psf. For the <br />test, the geocomposite shall be sandwiched between a layer of 60 -mil HDPE geomembrane and operations layer <br />soil. The minimum test duration shall be 100 hours and the report for the test results shall include <br />FORWARD LANDFILL WMU FU -06 GEOCOMPOSITE <br />02774 6 DRAINAGE NET <br />• <br />• <br />I <br />SPECIFIED <br />I <br />TEST <br />PROPERTIES <br />QUALIFIER <br />UNITS <br />VALUES") <br />METHOD <br />Geonet Component: <br />Polymer composition <br />Minimum <br />% <br />95 polyethylene <br />NIA <br />by weight <br />Polymer specific gravity <br />Minimum <br />— <br />0.935 <br />ASTM D 1505 <br />Polymer melt index <br />Maximum <br />g/10 min. <br />1.0 <br />ASTM D 1238 <br />Carbon black content <br />Range <br />% <br />2-3 <br />ASTM D 1603 <br />Foaming Agents <br />Maximum <br />% <br />0.0 <br />N/A <br />Nominal thickness <br />Minimum <br />mm <br />6 <br />ASTM D 5199 <br />Geotextile Filter Component: <br />Polymer composition <br />Minimum <br />% <br />95 polyester or <br />N/A <br />polypropylene <br />Mass per unit area <br />Minimum <br />oz/yd' <br />7 <br />ASTM D 5261 <br />(i/m) <br />Filter Requirements <br />Apparent opening size <br />Maximum <br />mm <br />095 < 0.18 mm <br />ASTM D 4751 <br />Permittivity <br />Minimum <br />1/s <br />>0.87 <br />ASTM D 4491 <br />Mechanical Requirements <br />Minimum <br />lb <br />160 <br />ASTM D 4632 <br />Grab strength <br />Tear strength <br />Minimum <br />lb <br />60 <br />ASTM D 4533 <br />Puncture strength <br />Minimum I <br />lb 1 <br />80 1 <br />ASTM D 4833 <br />Geocomposite: <br />Index Transmissivity (2) <br />Minimum <br />1112/s <br />2 x 10'3 <br />ASTM D 4716 <br />Performance Transmissivity <br />Minimum <br />m2/s <br />1 x 10"5 <br />ASTM D 4716 <br />(3) <br />Peel Strength/Ply Adhesion <br />Minimum <br />lb/in <br />1 <br />ASTM F 904 or <br />ASTM D 413 <br />Notes: <br />1.
