Designation:D7064/D7064M21Standard Practice forOpen-Graded Friction Course(OGFC)Asphalt MixtureDesign1This 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 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 Com-pactor(SGC)or other suitable forms of compaction.TheOGFC asphalt mixture design is based on the volumetricproperties of the asphalt mixture in terms of air voids and thepresence of stone-on-stone contact.Information found inGuide D6932/D6932M should be reviewed before starting themix design.Where applicable,Specification D3666 should beapplied as a minimum for agencies testing and inspecting roadand 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.Combiningvalues from the two systems may result in nonconformancewith the standard.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2C29/C29M Test Method for Bulk Density(“Unit Weight”)and Voids in AggregateC127 Test Method for Relative Density(Specific Gravity)and Absorption of Coarse AggregateC131/C131M Test Method for Resistance to Degradation ofSmall-Size Coarse Aggregate by Abrasion and Impact inthe Los Angeles MachineC136/C136M Test Method for Sieve Analysis of Fine andCoarse AggregatesC1252 Test Methods for Uncompacted Void Content of FineAggregate(as Influenced by Particle Shape,SurfaceTexture,and Grading)D946/D946M Specification for Penetration-Graded AsphaltBinder for Use in Pavement ConstructionD2041/D2041M Test Method for Theoretical MaximumSpecific Gravity and Density of Asphalt MixturesD2419 Test Method for Sand Equivalent Value of Soils andFine AggregateD3203/D3203M Test Method for Percent Air Voids in Com-pacted Asphalt MixturesD3381/D3381M Specification for Viscosity-Graded AsphaltBinder for Use in Pavement ConstructionD3666 Specification for Minimum Requirements for Agen-cies Testing and Inspecting Road and Paving MaterialsD4791 Test Method for Flat Particles,Elongated Particles,or Flat and Elongated Particles in Coarse AggregateD5821 Test Method for Determining the Percentage ofFractured Particles in Coarse AggregateD6114/D6114M Specification for Asphalt-Rubber BinderD6373 Specification for Performance-Graded AsphaltBinderD6390 Test Method for Determination of Draindown Char-acteristics in Uncompacted Asphalt MixturesD6752/D6752M Test Method for Bulk Specific Gravity andDensity of Compacted Asphalt Mixtures Using AutomaticVacuum Sealing MethodD6857/D6857M Test Method for Maximum Specific Grav-ity and Density of Asphalt Mixtures Using AutomaticVacuum Sealing MethodD6925 Test Method for Preparation and Determination ofthe Relative Density of Asphalt Mix Specimens by Meansof the Superpave Gyratory Compactor1This practice is under the jurisdiction of ASTM Committee D04 on Road andPaving Materials and is the direct responsibility of Subcommittee D04.23 onPlant-Mixed Asphalt Surfaces and Bases.Current edition approved May 1,2021.Published May 2021.Originallyapproved in 2004.Last previous edition approved in 2013 as D7064/D7064M 08(2013).DOI:10.1520/D7064_D7064M-21.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1D6926 Practice for Preparation of Asphalt Mixture Speci-mens Using Marshall ApparatusD6932/D6932M Guide for Materials and Construction ofOpen-Graded Friction Course Plant Mixtures2.2 AASHTO Standar
