Designation:D449/D449M03(Reapproved 2014)1Standard Specification forAsphalt Used in Dampproofing and Waterproofing1This standard is issued under the fixed designation D449/D449M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1NOTEUnits information was editorially corrected in January 2014.1.Scope1.1 This specification covers three types of asphalt suitablefor use as a mopping coat in dampproofing;or as a plying ormopping cement in the construction of membrane waterproof-ing systems with felts in accordance with Specification D226;fabrics in accordance with Specifications D173 or D1668(asphalt types);asphalt-impregnated glass mat in accordancewith Specifications D2178;and with primer in accordance withSpecification D41.1.2 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 should be used independently of the other.Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 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:2D5 Test Method for Penetration of Bituminous MaterialsD36 Test Method for Softening Point of Bitumen(Ring-and-Ball Apparatus)D41 Specification for Asphalt Primer Used in Roofing,Dampproofing,and WaterproofingD92 Test Method for Flash and Fire Points by ClevelandOpen Cup TesterD113 Test Method for Ductility of Bituminous MaterialsD140 Practice for Sampling Bituminous MaterialsD173 Specification for Bitumen-Saturated Cotton FabricsUsed in Roofing and WaterproofingD226 Specification for Asphalt-Saturated Organic Felt Usedin Roofing and WaterproofingD1668 Specification for Glass Fabrics(Woven and Treated)for Roofing and WaterproofingD2042 Test Method for Solubility of Asphalt Materials inTrichloroethyleneD2178 Specification for Asphalt Glass Felt Used in Roofingand WaterproofingD3461 Test Method for Softening Point ofAsphalt and Pitch(Mettler Cup-and-Ball Method)3.Classification3.1 Asphalts covered by this specification include threetypes:3.1.1 Type IA soft,adhesive,“self-healing”asphalt thatflows easily under the mop and is suitable for use below gradeunder uniformly moderate temperature conditions both duringthe process of installation and during service.NOTE1Type I asphalt is suitable for foundations,tunnels,subways,and so forth.3.1.2 Type IIA somewhat less susceptible asphalt thanType I,with good adhesive and“self-healing”properties,suitable for use above grade where it will not be exposed totemperatures exceeding 50C 122F.NOTE2Type II asphalt is suitable for railroad bridges,culverts,retaining walls,tanks,dams,conduits,spray decks,and so forth.3.1.3 Type IIIAn asphalt less susceptible to temperaturethan Type II,with good adhesive properties,and suitable foruse above grade on vertical surfaces exposed to direct sunlightor temperatures above 50C 122F.4.Materials and Manufacture4.1 The asphalt shall be prepared from crude petroleum bysuitable refining processes to conform to the applicable physi-cal requirements for each type.5.Physical Requirements5.1 The asphalt shall be homogeneous and free of water.1This specification is under the jurisdiction of ASTM Committee D08 onRoofing and Waterproofing and is the direct responsibility of Subcommittee D08.03on Surfacing and Bituminous Materials for Membrane Waterproofing and Built-upRoofing.Current edition approved Jan.1,2014.Published January 2014.Originallyapproved in 1937.Last previous edition approved in 2008 as D449 03(2008).DOI:10.1520/D0449_D0449M-03R14E01.2For 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 5.2 Each type shall conform to the appropriate requirementsprescribed in Table 1.6.Sampling and Test Methods6.1 Sample the material and determine the properties enu-merated in this specification in accordance with the followingmethods:6.1.1 SamplingPractice D140.6.1.2 Softening PointTest Methods D36 and D3461.6.1.3 Flash PointTest Method D92.6.1.4 PenetrationTest Method D5.6.1.5 DuctilityTest Method D113.6.1.6 Solubility in TrichloroethyleneTest Method D2042.7.Inspection and Certification7.1 Inspection and certification of the material shall be asagreed upon between the purchaser and the sell
