3、ification covers asphalt cements graded by viscosity at 60C 140F for use in pavement construction. ThreeFoursets of limits are offered in this specification. The purchaser shall specify the applicable table of limits. In the event the purchaserdoes not specify limits, Table 1 shall apply. For asphal

See Specification D946.If needed, volume corrections for asphalt cements should be made according to Practice D4311.1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in eachsystem may
5、not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from thetwo systems may result in non-conformance with the standard.2.
