Abstract
This specification covers the standard for asphalt cement proposed for use in the construction of pavements. This specification shall include the following penetration grades: 40-50, 60-70, 85-100, 120-150, and 200-300. The cements shall be manufactured by refining crude petroleum through suitable methods. The asphalt cement shall be homogeneous and shall not foam when heated to application temperature. Requirements such as ductility, flash point, solubility in trichloroethylene, and penetration shall be determined in accordance with ASTM test methods.
Scope
1.1 This specification covers asphalt cement for use in the construction of pavements.
1.2 This specification covers the following penetration grades:
| 40–50, | 120–150, and |
| 60–70, | 200–300. |
| 85–100, |
1.3 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.
