Standard Specification for Prefabricated Bituminous Geomembrane Used as Canal and Ditch Liner (Exposed Type)
Also Known As:
The ASTM D2643/D2643M-08 (R2019) standard is a specification that outlines the requirements for prefabricated bituminous geomembranes used as canal and ditch liners of the exposed type. These geomembranes are designed to provide a continuous lining for canals and ditches to prevent seepage and protect the surrounding soil.
According to the standard, the geomembranes should be composed of multiple layers of asphalt mastic sandwiched between asphalt-saturated felts, mats, or fabrics. They should be coated on both sides and covered with a material to prevent sticking during storage and shipment. The coating is typically a hot-applied asphalt material that may include a mineral stabilizer.
The standard specifies various tests that should be conducted to ensure the quality and performance of the prefabricated bituminous geomembranes. These tests include measuring the thickness of the asphalt coating, evaluating water absorption, determining the mass percent of asphalt, assessing resistance to decay, measuring flexibility and brittleness, and evaluating heat dissipation.
