This specification covers three sets of physical requirement limits for asphalt cements graded by viscosity at a specified temperature for use in pavement construction. The purchaser shall indicate the applicable table of limits. The cements shall be prepared from crude petroleum by suitable methods, and if needed, volume corrections should be made as well. The properties for which the materials shall be tested on and should conform to are water content, viscosity, penetration, Cleveland open cup flash point, solubility in trichloroethylene, ductility, and behavior during thin-film oven and rolling thin-film oven tests on residue.
