Designation:D2397/D2397M13Standard Specification forCationic Emulsified Asphalt1This standard is issued under the fixed designation D2397/D2397M;the number immediately following the designation indicates theyear of original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript 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 specification covers seven grades of cationic emul-sified asphalt for use in pavement construction in the mannerdesignated.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.2.Referenced Documents2.1 ASTM Standards:2D5 Test Method for Penetration of Bituminous MaterialsD113 Test Method for Ductility of Bituminous MaterialsD140 Practice for Sampling Bituminous MaterialsD244 Test Methods and Practices for Emulsified AsphaltsD2042 Test Method for Solubility of Asphalt Materials inTrichloroethyleneD3910 Practices for Design,Testing,and Construction ofSlurry SealD6930 Test Method for Settlement and Storage Stability ofEmulsified AsphaltsD6933 Test Method for Oversized Particles in EmulsifiedAsphalts(Sieve Test)D6935 Test Method for Determining Cement Mixing ofEmulsified AsphaltD6936 Test Method for Determining Demulsibility of Emul-sified AsphaltD6997 Test Method for Distillation of Emulsified AsphaltD7226 Test Method for Determining the Viscosity of Emul-sified Asphalts Using a Rotational Paddle ViscometerD7402 Practice for Identifying Cationic Emulsified AsphaltsD7496 Test Method for Viscosity of Emulsified Asphalt bySaybolt Furol ViscometerD7553 Test Method for Solubility of Asphalt Materials inN-Propyl Bromide3.Requirements3.1 The emulsified asphalt shall be tested within 14 days ofdelivery.The emulsified asphalt shall be homogeneous afterthorough mixing provided separation has not been caused byfreezing.Emulsions separated by freezing shall not be tested.3.2 Emulsified asphalt shall conform to the requirementsprescribed in Table 1 or Table 2.If no table is specified,thedefault is Table 1.4.Sampling4.1 Samples of emulsified asphalt shall be taken in accor-dance with Practice D140.4.2 Samples shall be stored in clean,airtight sealed contain-ers at a temperature of not less than 4C 39.2F until tested.5.Test Methods5.1 The properties of the emulsified asphalts given in Table1 or Table 2 shall be determined in accordance with thefollowing ASTM test methods:5.1.1 ViscosityTest Method D7496 for Table 1 or TestMethod D7226 for Table 2.5.1.2 Storage StabilityTest Method D6930.5.1.3 DemulsibilityTest Method D6936.5.1.4 Coating Ability and Water ResistanceTest MethodsD244.5.1.5 Particle ChargeTest Method D7402.5.1.6 Sieve TestTest Method D6933,except use distilledwater in all wetting and washing operations in place of thenonionic surfactant solution(1%).5.1.7 Cement MixingTest Method D6935.5.1.8 DistillationTest Method D6997.5.1.9 Tests on Residue from DistillationTest Methods D5,D113,D2042,and D7553.1This specification is under the jurisdiction of ASTM Committee D04 on Roadand Paving Materials and is the direct responsibility of Subcommittee D04.41 onEmulsified Asphalt Specifications.Current edition approved Dec.1,2013.Published January 2014.Originallyapproved in 1965.Last previous edition approved in 2012 as D2397 12.DOI:10.1520/D2397_D2397M-13.2For 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 TABLE 1 Requirements for Cationic Emulsified AsphaltTypeRapid-SettingMedium-SettingSlow-SettingQuick SettingGradeCRS-1CRS-2CMS-2CMS-2hCSS-1CSS-1hCQS-1hAminmaxminmaxminmaxminmaxminmaxminmaxminmaxTest on emulsions:Viscosity,Saybolt Furol at 25C 77F SFS201002010020100Viscosity,Saybolt Furol at 50C 122F SFS201001004005045050450Storage stability test,24-h,%B111111Demulsibility,35 mL,0.8%dioctyl sodiumsulfosuccinate,%40.40.Coating ability and water resistance:Coating,dry aggregateCoating,after sprayingCoating,wet aggregategoodfairfairgoodfairfairCoating,after sprayingfairfairParticle charge testpositivepositivepositivepositivepositivepositivepositiveSieve test,%B0.100.100.100.100.100.100.10Cement mixing test,%2.02.0N/ADistillation:Oil distillate,by volume of emulsion,%331212Residue,%60656565575757Tests on residue from distillation test:Penetration,25C 77F,100 g,5 s100250100250100250409010025040904090Ductility,25C 77F,5 cm/min,cm40404040404040Solubility in trichlo
