Designation:D6084/D6084M21Standard Test Method forElastic Recovery of Asphalt Materials by Ductilometer1This standard is issued under the fixed designation D6084/D6084M;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 test method assesses the elastic recovery of anasphalt material measured by the recoverable strain determinedafter severing an elongated briquet specimen of the material ofthe form described in 4.1.The specimens are pulled to aspecified distance at a specified speed and at a specifiedtemperature.Unless otherwise specified,the test shall be madeat a temperature of 25 6 0.5 C 77 6 0.9 F and with a speedof 5 cm/min 6 5%.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system are not necessarily exact equivalents;therefore,toensure conformance with the standard,each system shall beused independently of the other,and values from the twosystems shall not be combined.1.3 WarningMercury has been designated by the UnitedStates Environmental Protection Agency and many state agen-cies as a hazardous material that can cause central nervoussystem,kidney,and liver damage.Mercury,or its vapor,maybe hazardous to health and corrosive to materials.Cautionshould be taken when handling mercury and mercury-containing products.See the applicable Material Safety DataSheet(MSDS)for details and EPAs website(http:/www.epa.gov/mercury/index.htm)for additional information.Users should be aware that selling mercury and/or mercury-containing products in your state may be prohibited by statelaw.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.1.5 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.1.6 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:2C670 Practice for Preparing Precision and Bias Statementsfor Test Methods for Construction MaterialsD5/D5M Test Method for Penetration of Bituminous Mate-rialsD113 Test Method for Ductility of Asphalt MaterialsD1754/D1754M Test Method for Effects of Heat and Air onAsphaltic Materials(Thin-Film Oven Test)D2872 Test Method for Effect of Heat and Air on a MovingFilm of Asphalt(Rolling Thin-Film Oven Test)D3666 Specification for Minimum Requirements for Agen-cies Testing and Inspecting Road and Paving MaterialsD6934 Test Method for Residue by Evaporation of Emulsi-fied AsphaltD6997 Test Method for Distillation of Emulsified AsphaltD7403 Test Method for Determination of Residue of Emul-sified Asphalt by Low Temperature Vacuum DistillationD7497 Practice for Recovering Residue from EmulsifiedAsphalt Using Low-Temperature Evaporative TechniqueE1 Specification for ASTM Liquid-in-Glass ThermometersE11 Specification for Woven Wire Test Sieve Cloth and TestSievesE77 Test Method for Inspection and Verification of Ther-mometersE644 Test Methods for Testing Industrial Resistance Ther-mometersE1137/E1137M Specification for Industrial Platinum Resis-tance ThermometersE2251 Specification for Liquid-in-Glass ASTM Thermom-eters with Low-Hazard Precision Liquids1This test method is under the jurisdiction of ASTM Committee D04 on Roadand Paving Materials and is the direct responsibility of Subcommittee D04.44 onRheological Tests.Current edition approved Nov.1,2021.Published November 2021.Originallyapproved in 1997.Last previous edition approved in 2018 as D6084/D6084M 18.DOI:10.1520/D6084_D6084M-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.13.Significance and Use3.1
