Standard Specification for Viscosity-Graded Asphalt Cement for Use in Pavement Construction

ABSTRACT
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.
SCOPE
1.1 This specification covers asphalt cements graded by viscosity at 60°C [140°F] for use in pavement construction. Three sets of limits are offered in this specification. The purchaser shall specify the applicable table of limits. In the event the purchaser does not specify limits, Table 1 shall apply. For asphalt cements graded by penetration at 25°C [77°F]. See Specification D946. If needed, volume corrections for asphalt cements should be made according to Practice D4311.TABLE 1 Requirements for Asphalt Cement, Viscosity Graded at 60°C [140°F]Note 1—Grading based on original asphalt.

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.
