Abstract
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.
