Designation:D6932/D6932M21Standard Guide forMaterials and Construction of Open-Graded Friction CoursePlant Asphalt Mixtures1This standard is issued under the fixed designation D6932/D6932M;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 guide covers the construction of open-gradedfriction course(OGFC)plant asphalt mixtures.End-use speci-fications should be adopted to conform to job and userrequirements.Where applicable,Specification D3666 shouldbe applied as a minimum for agencies testing and inspectingroad and paving materials.1.2 Asphalt OGFCs are placed as the final wearing coursefor highways and airfields.1.3 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.1.4 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 AggregateC88/C88M Test Method for Soundness of Aggregates byUse of Sodium Sulfate or Magnesium SulfateC127 Test Method for Relative Density(Specific Gravity)and Absorption of Coarse AggregateC128 Test Method for Relative Density(Specific Gravity)and Absorption of Fine 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)D75/D75M Practice for Sampling AggregatesD140/D140M Practice for Sampling Asphalt MaterialsD448 Classification for Sizes of Aggregate for Road andBridge ConstructionD946/D946M Specification for Penetration-Graded AsphaltBinder for Use in Pavement ConstructionD1461 Test Method for Moisture or Volatile Distillates inAsphalt MixturesD2419 Test Method for Sand Equivalent Value of Soils andFine AggregateD2995 Practice for Estimating Application Rate and Re-sidual Application Rate of Bituminous DistributorsD3381/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 BinderD6307 Test Method for Asphalt Content of Asphalt Mixtureby Ignition MethodD6373 Specification for Performance-Graded AsphaltBinderD6390 Test Method for Determination of Draindown Char-acteristics in Uncompacted Asphalt MixturesD7064/D7064M Practice for Open-Graded Friction Course(OGFC)Mix Design1This guide 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 D6932/D6932M 08(2013).DOI:10.1520/D6932_D6932M-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.12.2 Other References:TRB NCHRP Synthesis 284 Performance Survey on Open-Graded Friction Course MixesNCAT Report No.2001-01 Design,Construction and Per-formance of New Generation Open-Graded FrictionCoursesFAA-RD-73-197FAA-RD-74-383.Terminology3.1 Definitions of Terms Specific to This Standard:3.1.1 open-graded friction course(OGFC),na specialtype of surface asphalt mixture used for reducing hydroplaningand potential for skidding,where the function of the mixture isto provide a free-draining layer that permits
