1.1 This specification covers prefabricated bituminous geomembranes intended to provide a continuous, exposed lining for canals and ditches.

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.


This specification covers prefabricated asphalt liner sheets intended for installation to provide a continuous, exposed lining for reservoirs, ponds, canals, and ditches. The liner sheets shall consist of layers of asphalt mastic between asphalt-saturated felts, mats, or fabrics, and shall be coated on both sides and covered with a material to prevent the finished sheets from sticking together during storage and shipment. The coating shall be a hot-applied asphalt material permitted to be compounded with a mineral stabilizer. Thickness of asphalt coating, water absorption, mass percent of asphalt, resistance to decay, flexibility, brittleness, and heat dissipation tests shall be performed to conform to the requirements specified.
