Historical (view previous versions of standard)
This specification covers four types of asphalt intended for use in built-up roof construction, construction of some modified bitumen systems, construction of bituminous vapor retarder systems, and for adhering insulation boards used in various types of roof systems. The asphalts shall be prepared from crude petroleum. Asphalts shall be classified as: Type I; Type II; Type III; and Type IV. Asphalts of each type shall conform to the physical properties prescribed. Tests shall be performed to determine the properties of the material in accordance with the following methods: sampling; softening point; flash point; penetration; ductility; and solubility.
