1、Designation:D3381/D3381M13Standard Specification forViscosity-Graded Asphalt Cement for Use in PavementConstruction1This standard is issued under the fixed designation D3381/D3381M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the
2、year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1.Scope1.1 This specification covers asphalt
3、cements graded byviscosity at 60C 140F for use in pavement construction.Four sets of limits are offered in this specification.Thepurchaser shall specify the applicable table of limits.In theevent the purchaser does not specify limits,Table 1 shall apply.For asphalt cements graded by penetration at 2
4、5C 77F.SeeSpecification D946.If needed,volume corrections for asphaltcements should be made according to Practice D4311.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsys
5、tem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.2.Referenced Documents2.1 ASTM Standards:2D5 Test Method for Penetration of Bituminous MaterialsD92 Test Method for Flash and Fire Points by ClevelandOpen Cup TesterD36 Te
