Designation:D818919Standard Test Method forTackiness of Asphalt Binders and Emulsified AsphaltResidue Using the Dynamic Shear Rheometer(DSR)1This standard is issued under the fixed designation D8189;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 covers the determination of pull-offforce and pull-off work of asphalt binders and emulsifiedasphalt residue by means of pull-off testing.The tackiness testis conducted using the dynamic shear rheometer(DSR)at oneor more temperatures.NOTE1This standard may be used for unconditioned material ormaterial conditioned in accordance with Test Method D2872.The major-ity of development work on this test method was performed on uncondi-tioned material.The emulsified asphalt residue should never be condi-tioned.1.2 A precision and bias statement for this standard has notbeen developed at this time.Therefore,this standard should notbe used for acceptance or rejection of a material for purchasingpurposes.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.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:2D8 Terminology Relating to Materials for Roads and Pave-mentsD2872 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 MaterialsD7175 Test Method for Determining the Rheological Prop-erties of Asphalt Binder Using a Dynamic Shear Rheom-eter3.Terminology3.1 For definitions of general terms used in this standard,refer to Terminology D8.3.2 Definitions:3.2.1 pull-off force,nthe maximum normal force,inNewtons,required to separate the upper plate of the DSRinstrument from the asphalt sample surface.3.2.2 pull-off work,nthe area under the force-versus-gapseparation curve,measured in Joules.3.2.3 tackiness,nthe measure of how sticky the asphaltbinder or emulsified asphalt residue is at a set temperature isshown in this test method by the combination of the pull-offforce and pull-off work.4.Summary of Test Method4.1 This test method is used to determine the tackiness ofasphalt binders and emulsified asphalt residue materials at agiven temperature,by means of pull-off testing.The sample istested in strain-control mode under tension.Testing a sample atdifferent temperatures(normal testing ranges can be 10 to70 C,correlating to pavement surface temperatures duringapplication)will allow for the determination of various degreesof tackiness due to field conditions.The sample preparationand apparatus are in accordance with Test Method D7175,1This test method is under the jurisdiction of ASTM Committee D04 on Roadand Paving Materials and is the direct responsibility of Subcommittee D04.47 onMiscellaneous Asphalt Tests.Current edition approved July 1,2019.Published July 2019.Originally approvedin 2019.DOI:10.1520/D8189-19.2For 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 using the 25-mm parallel plate geometry for the bottom plateand the 8-mm parallel plate geometry for the top plate.Theinitial gap is dependent on the sample thickness.Once thermalequilibrium is achieved,the top geometry is lowered to makecontact with the sample.After contact is made,a constantnormal force(10.0 6 0.5 N)is maintained in order to load t
