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.
