Designation:D700011Standard Test Method forSweep Test of Bituminous Emulsion 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 bituminous emulsion and aggregates bysimulating the brooming of a surface treatment in the labora-tory.1.2 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.3 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.1.4 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 and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2C127 Test Method for Relative Density(Specific Gravity)and Absorption of Coarse AggregateD8 Terminology Relating to Materials for Roads and Pave-mentsD75 Practice for Sampling AggregatesD140 Practice for Sampling Bituminous MaterialsD226 Specification for Asphalt-Saturated Organic Felt Usedin Roofing and WaterproofingD977 Specification for Emulsified AsphaltD2397 Specification for Cationic Emulsified Asphalt2.2 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 bituminous emulsions.A brush(designed toclosely replicate the sweeping action of a broom)exerts a forceon the aggregate used on surface treatments.Bituminousemulsion is applied to an asphalt felt disk.Aggregate is appliedand embedded into the bituminous emulsion.The sample isthen conditioned at a prescribed temperature and time periodbefore testing.A mixer abrades the surface of the sample usinga nylon brush.After one minute of abrasion,the test is stopped,any loose aggregate is removed,and the percent mass loss iscalculated.4.Significance and Use4.1 This test method is useful for classifying rapid-settingbituminous emulsions and is applicable to surface treatmentsthat require a quick return to traffic.It has the capability topredict surface treatment performance in the formative stageusing construction components.This performance test is in-tended to evaluate the potential curing characteristics of abinder-aggregate combination to ensure that the surface treat-ment is sufficiently cured before allowing traffic onto the seal.5.Apparatus5.1 Mixer4Use to abrade the sample.1This test method is under the jurisdiction of ASTM Committee D04 on Roadand Paving Materials and is the direct responsibility of Subcommittee D04.24 onBituminous Surface Treatments.Current edition approved June 1,2011.Published June 2011.Originallyapproved in 2004.Last previous edition approved in 2008 as D7000 08.DOI:10.1520/D7000-11.2For 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.4The sole source of supply of the Hobart Mixer13H.P.Fixed Speed Motor,model A 120,apparatus known to the committee at this time is Hobart Corporation,701 S.Ridge Ave.,Troy,OH 45374,http:/.If you are awareof alternative suppliers,please provide this information to ASTM InternationalHeadquarters.Your comments will receive careful consideration at a meeting of theresponsible technical committee,1which you may attend.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.2 Quick-clamp Mounting Base5This base must be anadequate and level support for clamping the sample in place.The test sample should not move during abrasion.5.3 PanAn appropriate pan will contain the test sample onthe mixer and hold dislodged aggregate.5.4 OvenThe conditioning oven shall be a constant tem-perature forced draft oven meeting the following requirementscontaining shelves with at least 65%voids.The shelves shallbe placed at least 120 mm apart and 100 mm away from the topand floor.Oven TypeForced draft ovenMin Inside D W H460 460 460 mmAccuracy1.0C5.5 BalanceA balance capable of weighing 800 g or moreto within 60.1 g.Aminimum platform length and width of 240mm is required.5.6 Removable Brush HolderThe brush holder shall beattachable to the mixer and capable of a free floating v
