Designation:D 5840 00Standard Specification forType II Polymer Modified Asphalt Cement for Use inPavement Construction1This standard is issued under the fixed designation D 5840;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(e)indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification covers asphalt cements that have beenmodified by the addition of an appropriate polymer for use inpavement construction.It was developed to provide a referencefor specifying polymer modified asphalt and reflects theproperties of currently available commercial products.Thetests are intended to measure compatibility and degree ofmodification,not performance characteristics.This is notintended to be a performance based specification.1.2 Type II polymer-modified asphalts are typically madewith styrene-butadiene rubber latex or polychloroprene latex.However,any polymer may be used that will give the requiredtest results when blended with the desired asphalt.2.Referenced Documents2.1 ASTM Standards:D 5 Test Method for Penetration of Bituminous Materials2D 92 Test Method for Flash and Fire Points by ClevelandOpen Cup3D 113 Test Method for Ductility of Bituminous Materials2D 140 Practice for Sampling Bituminous Materials2D 1754 Test Method for Effect of Heat andAir onAsphalticMaterials(Thin-Film Oven Test)2D 2170 Test Method for Kinematic Viscosity of Asphalts(Bitumens)2D 2872 Test Method for Effect of Heat andAir on a MovingFilm of Asphalt(Rolling Thin-Film Oven Test)2D 4957 Test Method for Apparent Viscosity of AsphaltEmulsion Residues and Non-Newtonian Bitumens byVacuum Capillary Viscometer2D 5801 Test Method for Toughness and Tenacity of Bitu-minous Materials23.Physical Requirements3.1 The polymer modified asphalt cement shall be homoge-neous,free from water and shall not foam when heated to347F(175C).3.2 The polymer modified asphalt cement shall conform tothe requirements of Table 1.3.3 The polymer modifier and the asphalt cement shall becompatible and pre-blended prior to use.4.Sampling and Test Methods4.1 Sample and test the polymer modified asphalt cement inaccordance with the following test methods and practices.4.1.1 SamplingPractice D 140.4.1.2 PenetrationTest Method D 5.4.1.3 Viscosity at 140F(60C)Test Method D 4957.4.1.4 Viscosity at 275F(135C)Test Method D 2170.4.1.5 DuctilityTest Method D 113.4.1.6 Flash Point,Cleveland Open CupTest MethodD 92.4.1.7 Rolling Thin-Film Oven TestTest Method D 2872.4.1.8 Thin-Film Oven TestTest Method D 1754.4.1.9 Toughness and TenacityTest Method D 5801.1This specification is under the jurisdiction of ASTM Committee D04 on Roadand Paving Materials and is under the direct responsibility of SubcommitteeD04.45on Modified Asphalt Specifications.Current edition approved Dec.10,2000.Published February 2001.Originallypublished as D 584095.Last previous edition D 584095.2Annual Book of ASTM Standards,Vol 04.03.3Annual Book of ASTM Standards,Vol 05.01.1Copyright ASTM,100 Barr Harbor Drive,West Conshohocken,PA 19428-2959,United States.The American Society for Testing and Materials takes no position respecting the validity of any patent rights asserted in connectionwith any item mentioned in this standard.Users of this standard are expressly advised that determination of the validity of any suchpatent rights,and the risk of infringement of such rights,are entirely their own responsibility.This standard is subject to revision at any time by the responsible technical committee and must be reviewed every five years andif not revised,either reapproved or withdrawn.Your comments are invited either for revision of this standard or for additional standardsand should be addressed to ASTM Headquarters.Your comments will receive careful consideration at a meeting of the responsibletechnical committee,which you may attend.If you feel that your comments have not received a fair hearing you should make yourviews known to the ASTM Committee on Standards,at the address shown below.This standard is copyrighted byASTM,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA19428-2959,United States.Individual reprints(single or multiple copies)of this standard may be obtained by contacting ASTM at the above address or at610-832-9585(phone),610-832-9555(fax),or serviceastm.org(e-mail);or through the ASTM website(www.astm.org).TABLE 1 Physical Property Requirements for Type II Polymer Modified AsphaltsDesignationII-AII-BII-CII-DMinMaxMinMaxMinMaxMinMaxTests on Original ProductPenetration at 77F(25C),100 g,5 s100708580Viscosity,140F(60C),1s 1,poise80016008001600Viscosity,275F(135C),cSt300300300300Ductility,39.2F(4C),5 cm/min,cm50502525Flash Point,COC,F(C)450(232)450(232)450(232)450(232)Toughness,77F(25C),20 in./min(51 cm/min),in.-lb(mN-m)75 8475110(12430)75(8475)110(12430)Tenacity,77F(25C),20 in./min(51 cm/min)
