Designation:D11307American Association StateHighway and Transportation Officials StandardAASHTO No.:T51Standard Test Method forDuctility of Bituminous Materials1This standard is issued under the fixed designation D113;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.This standard has been approved for use by agencies of the U.S.Department of Defense.1.Scope1.1 This test method describes the procedure for determin-ing the ductility of a bituminous material measured by thedistance to which it will elongate before breaking when twoends of a briquet specimen of the material,of the formdescribed in Section 4,are pulled apart at a specified speed andat a specified temperature.Unless otherwise specified,the testshall be made at a temperature of 25 6 0.5C and with a speedof 5 cm/min 6 5.0%.At other temperatures the speed shouldbe specified.1.2 Because of the large number of methods for obtainingtest samples,it is impractical to discuss specific products in thistest method.Refer to individual product specifications forguidance in obtaining a test sample.1.3 The values stated in SI units are to be regarded as thestandard.Values in parenthesis in inch-pound units are pro-vided for informational purposes only.1.4 WarningMercury has been designated by EPA andmany state agencies as a hazardous material that can causecentral nervous system,kidney and liver damage.Mercury,orits vapor,may be hazardous to health and corrosive tomaterials.Caution should be taken when handling mercury andmercury containing products.See the applicable product Ma-terial Safety Data Sheet(MSDS)for details and EPAs website(http:/www.epa.gov/mercury/faq.htm)for additional informa-tion.Users should be aware that selling mercury or mercurycontaining products,or both,in your state may be prohibited bystate law.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.2.Referenced Documents2.1 ASTM Standards:2C670 Practice for Preparing Precision and Bias Statementsfor Test Methods for Construction MaterialsD5 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)E1 Specification for ASTM Liquid-in-Glass ThermometersE11 Specification for Woven Wire Test Sieve Cloth and TestSievesE77 Test Method for Inspection and Verification of Ther-mometersE220 Test Method for Calibration of Thermocouples ByComparison TechniquesE644 Test Methods for Testing Industrial Resistance Ther-mometers3.Significance and Use3.1 This test method provides one measure of tensile prop-erties of bituminous materials and may be used to measureductility for specification requirements.4.Apparatus4.1 MoldThe mold shall be similar in design to that shownin Fig.1.The mold shall be made of brass,10.0 6 0.1 mmthick,the ends b and b being known as clips,and the parts aand a as sides of the mold,with a brass base plate that is largerthan the assembled mold.The dimensions of the assembledmold shall be as shown in Fig.1 with the permissible variationsindicated.4.2 Water Bath for Conditioning SpecimensA water bathcapable of maintaining the specified test temperature,varying1This 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 Dec.1,2007.Published January 2008.Originallyapproved in 1921.Last previous edition approved in 1999 as D113 99.DOI:10.1520/D0113-07.2For 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 States1 not more than 0.5C(0.9F)from this temperature.Thespecimen shall be immersed and supported such that it issurrounded by water.4.3 Testing MachineFor pulling the briquet of bituminousmaterial apart,any apparatus may be used which is soconstructed that the specimen will be continuously immersedin water,while the two clips are pulled apart at a uniformspeed,as specified,without undue vibration.A variation of65%is permissible.The water in the tank of the testingmachine shall cover the specimen both above and below it byat least 2.5 cm and shall be maintained within 60.5C(60.9F)of the test temperature.The testing machine shallincorpor
