The vendor rejected including PPA, however declined to expose what had actually been included in the binder. When pressed by the division of transport, the vendor revealed that it was adding what it called an asphalt extendernow understood to be re-refined engine oil bottoms (REOB). REOB includes a percentage of phosphorus, which is what division drug stores originally determined.


"Nobody understood this material was being contributed to asphalt, had actually seen any type of research study on just how this could affect performance of hot-mix asphalt pavements, or understood for for how long and exactly how commonly it was being made use of throughout the country," states Mueller. After conversations at the technical conference, he says, "It quickly went from being simply a concern in Illinois to coming to be a nationwide and global issue."
