Designation:D700019aStandard Test Method forSweep Test of Emulsified Asphalt Surface TreatmentSamples1This standard is issued under the fixed designation D7000;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 measures the curing performancecharacteristics of emulsified asphalt and aggregates by simu-lating the brooming of a surface treatment in the laboratory.1.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.3 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.1.4 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.1.5 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:2D75/D75M Practice for Sampling AggregatesD226/D226M Specification for Asphalt-Saturated OrganicFelt Used in Roofing and WaterproofingD3666 Specification for Minimum Requirements for Agen-cies Testing and Inspecting Road and Paving MaterialsE691 Practice for Conducting an Interlaboratory Study toDetermine the Precision of a Test Method2.2 ISSA Document:3ISSATechnical Bulletin No.100 Test Method for Wet TrackAbrasion of Slurry Surfaces3.Summary of Test Method3.1 The sweep test is effective for defining the film forma-tion stage of emulsified asphalt.A brush(designed to closelyreplicate the sweeping action of a broom)exerts a force on theaggregate used on surface treatments.Emulsified asphalt isapplied to an asphalt felt disk.Aggregate is applied andembedded into the emulsified asphalt.The sample is thenconditioned at a prescribed temperature and time period beforetesting.A mixer abrades the surface of the sample using anylon brush.After 1 min of abrasion,the test is stopped,anyloose aggregate is removed,and the percent mass loss iscalculated.4.Significance and Use4.1 This test method is useful for classifying rapid-settingemulsified asphalt and is applicable to surface treatments thatrequire a quick return to traffic.It has the capability to predictsurface treatment performance in the formative stage usingconstruction components.This performance test is intended toevaluate the potential curing characteristics of a binder-aggregate combination to ensure that the surface treatment issufficiently cured before allowing traffic onto the seal.NOTE1The quality of the results produced by this standard aredependent on the competence of the personnel performing the procedureand the capability,calibration,and maintenance of the equipment used.Agencies that meet the criteria of Specification D3666 are generallycapable 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 guideline provides a means of evaluating and1This test method is under the jurisdiction of ASTM Committee D04 on Roadand Paving Materials and is the direct responsibility of Subcommittee D04.24 onAsphalt Surface Treatments.Current edition approved Dec.15,2019.Published January 2020.Originallyapproved in 2004.Last previous edition approved in 2019 as D7000 19.DOI:10.1520/D7000-19A.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.3Available from International Slurry Surfacing Association(ISSA),3 ChurchCircle,PMB 250,Annapolis,MD 21401,http:/www.slurry.org.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.controlling some of those factors.5.Apparatus5.1 Mixer4Use to abrade
