The vendor refuted including PPA, yet decreased to expose what had actually been contributed to the binder. When pressed by the division of transportation, the supplier exposed that it was adding what it called an asphalt extendernow known to be re-refined engine oil bottoms (REOB).

"Nobody knew this material was being contributed to asphalt, had seen any study on exactly how this might influence efficiency of hot-mix asphalt pavements, or recognized for how long and how commonly it was being made use of throughout the nation," says Mueller.

As an example, the DSR makes it possible for item programmers to produce tooth paste with the appropriate consistency check my site to ensure that it can be pressed from a tube but not drop off the tooth brush.
