3、cification covers asphalt cements graded by viscosity at 60C 140F for use in pavement construction. Three setsof limits are offered in this specification. The purchaser shall specify the applicable table of limits. In the event the purchaser doesnot specify limits, Table 1 shall apply. For asphalt c
4、ements graded by penetration at 25C 77F. See Specification D946. Ifneeded, 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 not
