ASTM D3381-09

1.1 This specification covers asphalt cements graded by viscosity at 140°F (60°C) 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 77°F (25°C) (see Specification D 946). If needed, volume corrections for asphalt cements should be made according to Practice D 4311.

TABLE 1 Requirements for Asphalt Cement, Viscosity Graded at 140°F (60°C)

Note—Grading based on original asphalt.

^A If ductility is less than 100, material will be accepted if ductility at 60°F (15.5°C) is 100 minimum at a pull rate of 5 cm/min.

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.
