Designation:D580117Standard Test Method forToughness and Tenacity of Asphalt Materials1This standard is issued under the fixed designation D5801;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.Scope1.1 This test method describes the procedure for measuringthe toughness and tenacity of asphalt materials.Typically,thetest method has been used to characterize elastomer modifiedasphalts,although values for toughness and tenacity may beobtained for any type of polymer-modified or non-modifiedasphalt.1.2 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.2.1 ExceptionSample mass is given only in SI units.Sample mass as given in SI units should be regarded asstandard.No other units of sample mass are included in thisstandard.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 contain-ing products.See the applicable Material Safety Data Sheet(MSDS)for details and EPAs website http:/www.epa.gov/mercury/index.htm for additional information.Users shouldbe aware that selling mercury and/or mercury-containingproducts in your state may be prohibited by state law.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 and health practices and determine the applica-bility 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:2D5 Test Method for Penetration of Bituminous MaterialsD1754 Test Method for Effects of Heat and Air on AsphalticMaterials(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 MaterialsE1 Specification for ASTM Liquid-in-Glass ThermometersE77 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 Liquids3.Summary of Test Method3.1 Atension head of specified size and shape is pulled froman asphalt sample at a rate of 20 in./min(508 mm/min).Acontinuous record of the force-versus-elongation curve is madeand used to calculate the toughness and the tenacity of thesample.The test is run at room temperature 77 6 5 F(25 63 C),after the sample has been subjected to a specifiedtemperature history.3.2 Toughness is defined in this procedure as the total workrequired to completely separate the tension head from thesample under the specified test conditions.Tenacity is ameasure of the increasing force as the sample is stretched pastthe initial peak,and may indicate the type and amount of1This 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 June 1,2017.Published June 2017.Originallyapproved as Proposal P 243 in 1994.Last previous edition approved in 2012 asD5801 12.DOI:10.1520/D5801-17.2For 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.1 polyme
