1、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
2、 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 for
3、mulating 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 n
4、ame 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 addre
5、sses,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 fro
6、m 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-
7、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-mendation
