1、Designation:D4311/D4311M21Standard Practice forDetermining Asphalt Volume Correction to a BaseTemperature1This standard is issued under the fixed designation D4311/D4311M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of la
2、st revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice provides tables of volume correctionfactors which may be used to convert volumes of asphaltmeasured at differen
3、t temperatures to a volume at a standardbase temperature.These tables are applicable to all types ofasphalts except emulsified asphalts.1.2 This practice provides tables to convert asphalt volumesto 15 C 60 F from volumes measured at any temperaturefrom 25 to+275 C 0 to 500 F.1.3 The values stated i
4、n either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in nonconformancewith the standard.NOTE1Correction
