Designation:D8051/D8051M16Standard Specification forWax-Modified Asphalt Used in Roofing1This standard is issued under the fixed designation D8051/D8051M;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.1.Scope1.1 This specification covers wax-modified asphaltic prod-ucts intended for use in built-up roof construction,constructionof bituminous vapor retarder systems,adhering fleece-backedsingle-ply roof membranes,and adhering insulation boardsused in various types of roof systems.The specification isintended for general classification purposes only,and does notimply restrictions on roofing system design,such as the slopeat which this asphalt may be used.1.2 These products have lower application temperaturescompared to products specified by Specification D312/D312M.1.3 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.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:2D5/D5M Test Method for Penetration of Bituminous Mate-rialsD36/D36M Test Method for Softening Point of Bitumen(Ring-and-Ball Apparatus)D92 Test Method for Flash and Fire Points by ClevelandOpen Cup TesterD113 Test Method for Ductility of Bituminous Materials(Withdrawn 2016)3D140/D140M Practice for Sampling Asphalt MaterialsD312/D312M Specification for Asphalt Used in RoofingD1079 Terminology Relating to Roofing and WaterproofingD2042 Test Method for Solubility of Asphalt Materials inTrichloroethyleneD3461 Test Method for Softening Point ofAsphalt and Pitch(Mettler Cup-and-Ball Method)D4402/D4402M Test Method for Viscosity Determination ofAsphalt at Elevated Temperatures Using a RotationalViscometerD7553 Test Method for Solubility of Asphalt Materials inN-Propyl Bromide3.Terminology3.1 For definitions of terms used in this specification,referto Terminology D1079.3.2 Definitions:3.2.1 high melt-point synthetic wax,nsynthetic wax with amelt point greater than 90C,for example polyethylene wax,oxidized polyethylene wax,Fischer-Tropsch wax,and ethylenebis stearamide wax.3.2.2 lightly oxidized asphalt,nhaving a softening pointand penetration range as defined in Table 1.3.2.3 wax-modified asphalt(WM),na product made bymodifying a lightly oxidized asphalt with a high melt-pointsynthetic wax.4.Materials and Manufacture4.1 The base asphalt shall be prepared from lightly oxidizedpetroleum asphalt.4.2 The wax-modified asphalt shall incorporate one or morehigh melt-point synthetic waxes in order to meet the require-ments of this specification.5.Physical Properties5.1 The products 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 July 1,2016.Published July 2016.DOI:10.1520/D8051_D8051M-16.2For 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.3The last approved version of this historical standard is referenced onwww.astm.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.2 The products of each type shall conform to the physicalproperties prescribed 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/D140M.6.1.2 Softening PointSee Test Methods D36/D36M orD3461.In cases where a disagreement exists between thepurchaser and the seller,Test Method D36/D36M shall be usedas the referee method.6.1.3 Flash PointTest Method D92.6.1.4 PenetrationTest Method D5/D5M.6.1.5 DuctilityTest Method D113.6.1.6 SolubilityTest Method D2042 or Test MethodD7553.In cases where a disagreement exists between thepurchaser and the seller,Test Method D2042 shall be used asthe referee method.6.1.7 EVTTest Method D4402/D4402M is used to deter-mine what temperatures result in the viscosity values thatdefine EVT for mopping and mechanical application.7.Inspection7.1 Inspection of the material shall be agreed upon
