The supplier refuted including PPA, yet declined to reveal what had actually been included in the binder. When pushed by the department of transportation, the vendor revealed that it was including what it called an asphalt extendernow recognized to be re-refined engine oil bases (REOB). REOB has a tiny quantity of phosphorus, which is what department chemists initially identified.


"No person recognized this material was being contributed to asphalt, had actually seen any type of research study on how this could affect efficiency of hot-mix asphalt sidewalks, or understood for how much time and just how commonly it was being used throughout the nation," states Mueller. After discussions at the technical conference, he says, "It quickly went from being just a concern in Illinois to ending up being a national and international worry."

A maker called a vibrant shear rheometer (DSR) was presented to the industry throughout the Strategic Highway Research Program's research job, which ran from 1987 to 1992.
