Designation:D1754/D1754M09(Reapproved 2014)Standard Test Method forEffects of Heat and Air on Asphaltic Materials(Thin-FilmOven Test)1This standard is issued under the fixed designation D1754/D1754M;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 test method covers the determination of the effectsof heat and air on a film of semisolid asphaltic materials.Theeffects of this treatment are determined from measurements ofselected asphalt properties before and after the test.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.1.3 WarningMercury has been designated by the UnitedStates Environmental Protection Agency and many state agen-cies as a hazardous material that can cause central nervoussystem,kidney and liver damage.Mercury,or its vapor,may behazardous to health and corrosive to materials.Caution shouldbe taken when handling mercury and mercury containingproducts.See the applicable Material Safety Data Sheet(MSDS)for details and EPAs websitehttp:/www.epa.gov/mercury/index.htmfor additional information.Users shouldbe aware that selling mercury and/or mercury containingproducts into your state may be prohibited by state law.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 Test Method for Penetration of Bituminous MaterialsD113 Test Method for Ductility of Bituminous MaterialsD2170 Test Method for Kinematic Viscosity of Asphalts(Bitumens)D2171 Test Method for Viscosity of Asphalts by VacuumCapillary ViscometerD3666 Specification for Minimum Requirements for Agen-cies Testing and Inspecting Road and Paving MaterialsD4753 Guide for Evaluating,Selecting,and Specifying Bal-ances and Standard Masses for Use in Soil,Rock,andConstruction Materials TestingE1 Specification for ASTM Liquid-in-Glass ThermometersE145 Specification for Gravity-Convection and Forced-Ventilation OvensE1137/E1137M Specification for Industrial Platinum Resis-tance Thermometers3.Summary of Test Method3.1 A film of asphaltic material is heated in an oven for 5 hat 163C 325F.The effects of heat and air are determinedfrom changes incurred in physical properties measured beforeand after the oven treatment.An optional procedure is providedfor determining the change in sample mass.3.2 Precision values for the method have been developed forviscosity,viscosity change,penetration change,mass change,and ductility.4.Significance and Use4.1 This method indicates approximate change in propertiesof asphalt during conventional hot-mixing at about 150C302F as indicated by viscosity,penetration,or ductilitymeasurements.It yields a residue which approximates theasphalt condition as incorporated in the pavement.If themixing temperature differs appreciably from the 150C302F level,more or less effect on properties will occur.NOTE1The quality of the results produced by this standard aredependent on the competence of the personnel performing the procedureand the capability,calibration,and maintenance of the equipment used.Agencies that meet the criteria of Specification D3666 are generallyconsidered capable of competent and objective testing and sampling.5.Apparatus5.1 OvenThe oven shall be electrically heated and shallconform to the performance requirements of Specification1This test method is under the jurisdiction of ASTM Committee D04 on Roadand Paving Materials and is the direct responsibility of Subcommittee D04.46 onDurability and Distillation Tests.Current edition approved June 1,2014.Published November 2014.Originallyapproved in 1960.Last previous edition approved in 2009 as D1754/D1754M 09.DOI:10.1520/D1754_D1754M-09R14.2For 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 E145,Type IB(Gravity-Convection),for operating tempera-tures up to 180C 356F.During the tests for compliance toSpecification E145 requirements,the oven shelf,properlycentered as described in 5.1.2 shall be in place and rotating.5.1.1 ConstructionThe oven shall be rectangular,and eachinterior dimension(exclusive of space o
