1.1 This specification covers geocomposite drainage panels used in highway, turf, and other high volume subsurface drainage applications. These products consist of a geotextile wrapped around a polymer core. These products are a minimum of 25 mm (1 in.) thick and are available in 150 mm (6 in.), 300 mm (12 in.), 450 mm (18 in.), and 600 mm (24 in.) widths.
1.2 The requirements of this specification are intended to provide a subsurface drainage geocomposite suitable for drainage of surface and subsurface water, sewerage, and leachates. Products produced in accordance with this specification and intended for pavement drainage applications shall be installed in accordance with Practice D6088.
1.3 The values as stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.
