1、Designation:D7064/D7064M08(Reapproved 2013)Standard Practice forOpen-Graded Friction Course(OGFC)Mix Design1This standard is issued under the fixed designation D7064/D7064M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of
2、last 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 covers the mix design of open-gradedfriction course(OGFC)using the superpave gyratory compac-tor(SGC)or other
3、 suitable forms of compaction.The OGFCmix design is based on the volumetric properties of the mix interms of air voids,and the presence of stone-on-stone contact.Information found in Guide D6932 should be reviewed beforestarting the mix design.Where applicable,Specification D3666should be applied as
4、 a minimum for agencies testing andinspecting road and paving materials.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,eachsystem shall be used independently of the other.Com
