Designation:D823921aStandard Specification forPerformance-Graded Asphalt Binder Using the MultipleStress Creep and Recovery(MSCR)Test1This standard is issued under the fixed designation D8239;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1This specification2covers asphalt binders graded byperformance.Grading designations are related to the LTPP-Bind calculated maximum pavement design temperature,theminimum pavement design temperature,and the traffic loading.NOTE1For more information on LTPPBind online,see https:/infopave.fhwa.dot.gov/Tools/LTPPBindOnline accessed June 10,2020.1.2 This specification incorporates Test Method D7405 fordetermining non-recoverable creep compliance,Jnr.“S,”“H,”“V,”or“E”designations must be specified for standard,heavy,very heavy,and extremely heavy traffic loading,respectively.1.3 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.4 The text of this standard references notes and footnoteswhich provide explanatory material.These notes and footnotes(excluding those in tables and figures)shall not be consideredas requirements of the standard.NOTE2A guidance document for specifying bodies using R%forelastic properties is under development.NOTE3For asphalt binders graded by penetration at 25 C,seeSpecification D946/D946M.For asphalt binders graded by viscosity at60 C,see Specification D3381/D3381M.For performance-graded asphaltbinder,see Specification D6373.NOTE4AASHTO R 29 provides non-mandatory information fordetermining the performance grade of an asphalt binder.1.5 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:3D8 Terminology Relating to Materials for Roads and Pave-mentsD92 Test Method for Flash and Fire Points by ClevelandOpen Cup TesterD95 Test Method for Water in Petroleum Products andBituminous Materials by DistillationD140/D140M Practice for Sampling Asphalt MaterialsD946/D946M Specification for Penetration-Graded AsphaltBinder for Use in Pavement ConstructionD2042 Test Method for Solubility of Asphalt Materials inTrichloroethyleneD2872 Test Method for Effect of Heat and Air on a MovingFilm of Asphalt(Rolling Thin-Film Oven Test)D3381/D3381M Specification for Viscosity-Graded AsphaltBinder for Use in Pavement ConstructionD4402/D4402M Test Method for Viscosity Determination ofAsphalt at Elevated Temperatures Using a RotationalViscometerD6373 Specification for Performance-Graded AsphaltBinderD6521 Practice for Accelerated Aging of Asphalt BinderUsing a Pressurized Aging Vessel(PAV)D6648 Test Method for Determining the Flexural CreepStiffness of Asphalt Binder Using the Bending BeamRheometer(BBR)D6723 Test Method for Determining the Fracture Propertiesof Asphalt Binder in Direct Tension(DT)(Withdrawn2021)4D7175 Test Method for Determining the Rheological Prop-erties of Asphalt Binder Using a Dynamic Shear Rheom-eterD7405 Test Method for Multiple Stress Creep and Recovery(MSCR)of Asphalt Binder Using a Dynamic ShearRheometer1This specification is under the jurisdiction of ASTM Committee D04 on Roadand Paving Materials and is the direct responsibility of Subcommittee D04.40 onAsphalt Specifications.Current edition approved June 15,2021.Published July 2021.Originallyapproved in 2018.Last previous edition approved in 2021 as D8239 21.DOI:10.1520/D8239-21A.2This specification is based on SHRP Product 1001,AASHTO M 320,andAASHTO M 332.3For 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.4The last approved version of this historical standard is referenced onwww.astm.org.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.1D7553 Test Method for Solubility of Asphalt Materials inN-Propyl Bromide2.2 AASHTO Standards:5R 29 Practice for Grading or Verifying the PerformanceGrade of an Asphalt BinderM 332 Specification for Performance-Graded AsphaltBinder Using Multiple Stress Creep Recovery(MSCR)Test3.Terminology3.1 Definitio
