Standard Specification for Asphalt Used in Canal, Ditch, and Pond Lining
Also Known As:
The ASTM D2521/D2521M-76 (R2021) standard defines the requirements for oxidized petroleum asphalt used as a waterproof membrane in the lining of canals, ditches, and ponds.
The standard specifies the procedures for sampling, testing, and assessing the physical properties of the asphalt material. The asphalt is expected to be applied in a sufficient thickness over a suitable subgrade and covered with an appropriate cover material to ensure its function as an effective waterproof membrane.
The standard outlines various properties that the asphalt should conform to: softening point (ring and ball), penetration points, ductility, flash point (Cleveland open cup), solubility in trichloroethylene, and loss in heating. These properties are examined through specific testing methods to ensure compliance with the standard.
