Designation:D3381/D3381M13Standard Specification forViscosity-Graded Asphalt Cement for Use in PavementConstruction1This standard is issued under the fixed designation D3381/D3381M;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 Department of Defense.1.Scope1.1 This specification covers asphalt cements graded byviscosity at 60C 140F for use in pavement construction.Four sets of limits are offered in this specification.Thepurchaser shall specify the applicable table of limits.In theevent the purchaser does not specify limits,Table 1 shall apply.For asphalt cements graded by penetration at 25C 77F.SeeSpecification D946.If needed,volume corrections for asphaltcements should be made according to Practice D4311.1.2 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 MaterialsD92 Test Method for Flash and Fire Points by ClevelandOpen Cup TesterD36 Test Method for Softening Point of Bitumen(Ring-and-Ball Apparatus)D70 Test Method for Density of Semi-Solid BituminousMaterials(Pycnometer Method)D95 Test Method for Water in Petroleum Products andBituminous Materials by DistillationD113 Test Method for Ductility of Bituminous MaterialsD140 Practice for Sampling Bituminous MaterialsD946 Specification for Penetration-Graded Asphalt Cementfor Use in Pavement ConstructionD1754 Test Method for Effects of Heat and Air on AsphalticMaterials(Thin-Film Oven Test)D2042 Test Method for Solubility of Asphalt Materials inTrichloroethyleneD2170 Test Method for Kinematic Viscosity of Asphalts(Bitumens)D2171 Test Method for Viscosity of Asphalts by VacuumCapillary ViscometerD2872 Test Method for Effect of Heat and Air on a MovingFilm of Asphalt(Rolling Thin-Film Oven Test)D4311 Practice for Determining Asphalt Volume Correctionto a Base TemperatureD7553 Test Method for Solubility of Asphalt Materials inN-Propyl Bromide3.Manufacture3.1 The asphalt cement shall be prepared from crude petro-leum by suitable methods.4.Physical Requirements4.1 The asphalt cement shall be homogeneous,free fromwater,and shall not foam when heated to 177C 350F.4.2 The asphalt cements shall conform to the requirementsgiven in Table 1,Table 2,Table 3,or Table 4,as specified bythe purchaser.5.Methods of Sampling and Testing5.1 Sample and test asphalt cements in accordance with thefollowing methods:5.1.1 SamplingPractice D140.5.1.2 WaterTest Method D95.5.1.3 Viscosity at 60C 140FTest Method D2171.5.1.4 Viscosity at 135C 275FTest Method D2170.5.1.5 Penetration Test Method D5.5.1.6 Flash Point,Cleveland Open CupTest Method D92.5.1.7 Solubility in TrichloroethyleneTest Method D2042.5.1.8 Thin-Film Oven TestTest Method D1754(see Table1 and Table 2).5.1.9 Rolling Thin-Film Oven TestTest Method D2872(see Table 3 and Table 4).5.1.10 DuctilityTest Method D113.1This specification is under the jurisdiction of ASTM Committee D04 on Roadand Paving Materials and is the direct responsibility of Subcommittee D04.40 onAsphalt Specifications.Current edition approved June 1,2013.Published July 2013.Originally approvedin 1975.Last previous edition approved in 2012 as D3381/D3381M 12.DOI:10.1520/D3381_D3381M-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 5.1.11 Softening pointTest Method D36.5.1.12 DensityTest Method D70.5.1.13 Solubility in N-propyl BromideTest MethodD7553.6.Keywords6.1 asphalt cements;bitumen;pavements;viscosityTABLE 1 Requirements for Asphalt Cement,Viscosity Graded at 60C 140F Based on Original AsphaltTestViscosity GradeAC-2.5AC-5AC-10AC-20AC-30AC-40Viscosity,60C 140F,Pas25 550 10100 20200 40300 60400 80Viscosity,135C 275F,min,mm2/s80110150210250300Penetration,25C 77F,100 g,5 s,min20012070403020Flash point,Cleveland open cup,min,C F165 325175 350220 425230 450230 450230 450Solubility in trichloroethylene,Amin,%99.099.099.099.099.099.0Tests on residue from thin-film oven test:Viscosity,60C 140F,max,Pas125250500100015002000Ductility,25C 77F,5 cm/min,min,cm100B10050201510ASolubility in N-Propyl Bromide can be an alternate method to Solubility in TCE.BIf ductility is less than 100,material will be accepted if ductility at 15C 60F is 100 mi
