This specification covers cutback petroleum asphalts of the rapid-curing type for use in the construction and treatment of pavements. The cutback asphalt shall not foam when heated to application temperature and shall conform to the requirements prescribed for the following: (1) kinematic viscosity, (2) flash point, (3) distillate content, (4) amount of residue from distillation, (5) properties of residue from distillation such as viscosity, ductility, and solubility in trichloroethylene, and (6) water content. The properties enumerated shall be determined by the specified test methods including tag open-cup flash point, distillation, and penetration tests.
