(Specification)Standard Specification for Re-Refined Engine Oil Bottoms (REOB)/Vacuum Tower Asphalt Extender (VTAE)
Standard Specification for Re-Refined Engine Oil Bottoms (REOB)/Vacuum Tower Asphalt Extender (VTAE)
ABSTRACT
This specification establishes the material, manufacturing, and physical requirements for re-refined engine oil bottoms, also known as vacuum tower asphalt extender, that may be used in formulating asphalt for pavement construction and roofing. "Re-refined engine oil bottoms" (REOB) is the commonly used term used by many state highway agencies and FHWA, while "vacuum tower asphalt extender" (VTAE) is preferred by manufacturers. REOB/VTAE may be obtained by processing used engine oil using atmospheric distillation followed by vacuum distillation to produce a vacuum residuum meeting the requirements outlined in this specification. The REOB/VTAE shall be homogenous, free from water, and not foam when heated to 232°C (450°F).
SCOPE
1.1 This specification covers re-refined engine oil bottoms, also known as vacuum tower asphalt extender, that may be used in formulating asphalt for pavement construction and roofing. This specification has been developed specifically for these two categories 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 bottoms” (REOB) is the prevailing name used by many state highway agencies and FHWA, while “vacuum tower asphalt extender” (VTAE) is the preferred name used by the manufacturers of the product. Since each name provides an important descriptor of production elements (“re-refined” and “vacuum tower”) for the specific product this specification addresses, this specification uses the term “REOB/VTAE.”
1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values 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 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 responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
