Designation:D846722Standard Test Method forDetermination of Emulsified Asphalt Residue By Quick Boil1This standard is issued under the fixed designation D8467;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 a quick and quantitative deter-mination of residue in emulsified asphalts giving comparableresults to Test Methods D6934,D6997,and D7404.1.2 Since a precision estimate for this standard has not beendeveloped,the test method is to be used for research andinformational purposes only.Therefore,this standard shouldnot be used for acceptance or rejection of a material forpurchasing purposes.1.3 The values stated in SI units are to be regarded as thestandard.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:2D3666 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 AsphaltD7404 Test Method for Determination of EmulsifiedAsphaltResidue by Moisture Balance Analyzer3.Summary of Test Method3.1 A known mass of emulsified asphalt is heated toevaporate water present,then re-weighed to determine thepercentage of asphalt residue by mass percent.4.Significance and Use4.1 This test method can be used for quantitative determi-nation of residue in emulsified asphalts.NOTE1The quality of results produced by this standard is dependenton the competence of the personnel performing the procedure and thecapability,calibration,and maintenance of the equipment used.Agenciesthat meet the criteria of Specification D3666 are generally consideredcapable of competent and objective testing,sampling,inspection,etc.Users of this standard are cautioned that compliance with SpecificationD3666 alone does not completely ensure reliable results.Reliable resultsdepend on many factors;following the suggestions of Specification D3666or some similar acceptable guidance provide a means of evaluating andcontrolling some of those factors.5.Apparatus5.1 Metal container or other suitable container with aminimum capacity of 300 mL.5.2 Balance,capable of weighing the metal container andemulsified asphalt to within 0.1 g.5.3 Hot plate.5.4 Oven(optional),capable of maintaining a temperatureof approximately 135 to 163 C.5.5 Tongs or similar tool.5.6 Screen(optional),to prevent splatter.6.Conditioning6.1 All emulsified asphalts shall be properly stirred toachieve homogeneity before testing.6.2 All emulsified asphalts with viscosity testing require-ments of 50 C shall be heated to 50 6 3 C in the originalsample container in a water bath or oven.The container shouldbe vented to relieve pressure.After the sample reaches 50 63 C,stir the sample to achieve homogeneity.1This test method is under the jurisdiction of ASTM Committee D04 on Roadand Paving Materials and is the direct responsibility of Subcommittee D04.42 onEmulsified Asphalt Test.Current edition approved June 15,2022.Published June 2022.DOI:10.1520/D8467-22.2For 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.16.3 Emulsified asphalts with viscosity testing requirementsof 25 C shall be conditioned to 25 6 3 C in the originalsample container to achieve homogeneity.After the samplereaches 25 6 3 C,stir the sample t
