Designation: D 7001 – 04

Standard Specification for

Geocomposites for Pavement Edge Drains and Other HighFlow Applications1
This standard is issued under the fixed designation D 7001; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.

1. Scope 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 regulatoryrequirements prior to use. 2.
