Designation:D812518Standard Specification forRe-Refined Engine Oil Bottoms(REOB)/Vacuum TowerAsphalt Extender(VTAE)1This standard is issued under the fixed designation D8125;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()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification covers re-refined engine oil bottoms,also known as vacuum tower asphalt extender,that may beused in formulating asphalt for pavement construction androofing.This specification has been developed specifically forthese two categories of product and is not intended for otheruses.Table 1 is to be used for pavement construction and Table2 for roofing.“Re-refined engine oil bottoms”(REOB)is theprevailing name used by many state highway agencies andFHWA,while“vacuum tower asphalt extender”(VTAE)is thepreferred name used by the manufacturers of the product.Sinceeach name provides an important descriptor of productionelements(“re-refined”and“vacuum tower”)for the specificproduct this specification addresses,this specification uses theterm“REOB/VTAE.”1.2 UnitsThe values stated in either SI units or inch-pound units are to be regarded separately as standard.Thevalues stated in each system may not be exact equivalents;therefore,each system shall be used independently of the other.Combining values from the two systems may result in noncon-formance with 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,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D92 Test Method for Flash and Fire Points by ClevelandOpen Cup TesterD93 Test Methods for Flash Point by Pensky-MartensClosed Cup TesterD95 Test Method for Water in Petroleum Products andBituminous Materials by DistillationD140/D140M Practice for Sampling Asphalt MaterialsD2042 Test Method for Solubility of Asphalt Materials inTrichloroethyleneD2872 Test Method for Effect of Heat and Air on a MovingFilm of Asphalt(Rolling Thin-Film Oven Test)D4402/D4402M Test Method for Viscosity Determination ofAsphalt at Elevated Temperatures Using a RotationalViscometerD7553 Test Method for Solubility of Asphalt Materials inN-Propyl BromideD8078 Test Method for Ash Content of Asphalt and Emul-sified Asphalt ResiduesE1131 Test Method for Compositional Analysis by Thermo-gravimetry3.Materials and Manufacture3.1 REOB/VTAE shall be the product of processing usedengine oil using atmospheric distillation followed by vacuumdistillation to produce a vacuum residuum meeting the speci-fications outlined in Table 1 or Table 2.4.Physical Requirements4.1 The REOB/VTAE shall be homogenous,free fromwater,and not foam when heated to 232 C(450 F).4.2 The REOB/VTAE shall conform to the requirementsgiven in Table 1 or Table 2 based on the intended end use.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 July 1,2018.Published July 2018.Originally approvedin 2017.Last previous edition approved in 2017 as D8125 17.DOI:10.1520/D8125-18.2For 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 StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 5.Methods of Sampling and Testing5.1 Sample and test the REOB/VTAE in accordance withthe following methods:5.1.1 SamplingPractice D140/D140M.5.1.2 WaterTest Method D95.5.1.3 Flash Point,Cleveland Open CupTest Method D92.5.1.4 Flash Point,Pensky Martin Closed CupTest MethodD93.5.1.5 Rolling Thin Film Oven TestTest Method D2872.5.1.6 SolubilityTest Method D2042 or D7553.5.1.7 Rotational Viscosity at 60 C(140 F)Test MethodD4402/D4402M.5.1.8 Ash ContentTest Method D8078 or E1131.6.Keywords6.1 asphalt;pavement;re-refined engine oil bottoms;r
