This specification establishes the property requirements and tests for cutback petroleum asphalts of the slow-curing type for use in the construction and treatment of pavements. The asphalt shall not foam when heated to application temperature and shall conform to the following requirements when undergone through appropriate tests: flash point (Cleveland open cup); kinematic viscosity; distillation (total distillate volume); asphalt residue; ductility; solubility in trichloroethylene; and water content.

1.1 This specification covers cutback petroleum asphalts of the slow-curing type for use in the construction and treatment of pavements.

1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
