The vendor denied adding PPA, however decreased to reveal what had actually been included to the binder. When pressed by the division of transport, the supplier revealed that it was including what it called an asphalt extendernow known to be re-refined engine oil bases (REOB). REOB includes a percentage of phosphorus, which is what department chemists originally identified.

"No one recognized this product was being contributed to asphalt, had seen any study on exactly how this might influence efficiency of hot-mix asphalt pavements, or knew for for how long and just how extensively it was being utilized throughout the nation," claims Mueller. After conversations at the technical conference, he says, "It rapidly went from being just an issue in Illinois to ending up being a national and worldwide worry." Part of the objective of the Chemistry Research Laboratory at TFHRC is to create brand-new examination techniques.
