The Asphalt Institute’s Technical Advisory Committee has formed a task force on re-refined engine oil bottoms (REOB), also known as Vacuum Tower Asphalt Extender (VTAE). The objectives of this REOB task force are to:

  • Learn more about REOB/VTAE materials, processing, effects/benefits  when blended in asphalt and best practices.
  • Recommend a course of action for Asphalt Institute that could include sponsoring a symposium, conducting research and/or developing information and guidance on REOB modification that may be similar to IS-220 for PPA modification.

Toward those objectives, the task force has developed this repository of REOB/VTAE information and wanted to share it with industry.
