1、Designation: D8125 17D8125 18Standard 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 revisi
2、on, 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,
3、that may be used informulating asphalt for pavement construction and roofing. This specification has been developed specifically for these twocategories of product and is not intended for other uses. Table 1 is to be used for pavement construction and Table 2 for roofing.“Re-refined engine oil botto
4、ms” (REOB) is the prevailing name used by many state highway agencies and FHWA, while “vacuumtower asphalt extender” (VTAE) is the preferred name used by the manufacturers of the product. Since each name provides animportant descriptor of production elements (“re-refined” and “vacuum tower”) for the
5、 specific product this specification addresses,this specification uses the term “REOB/VTAE.”1.2 UnitsThe values stated in either SI units or inch-pound units are to be regarded separately as standard. The values statedin each system may not be exact equivalents; therefore, each system shall be used
6、independently of the other. Combining valuesfrom the two systems may result in nonconformance with the standard.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibilityof the user of this standard to establish appropriate saf
7、ety, health, and environmental practices and determine the applicability ofregulatory limitations prior to use.1.4 This international standard was developed in accordance with internationally recognized principles on standardizationestablished in the Decision on Principles for the Development of Int
