1.1This 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.

1.2The 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.
