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.

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

1.2 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 nonconformance with the standard.

1.3 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
