The vendor denied adding PPA, but declined to reveal what had been contributed to the binder. When pushed by the department of transportation, the supplier exposed 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 drug stores at first identified.


"No one knew this product was being contributed to asphalt, had seen any research on how this may influence efficiency of hot-mix asphalt pavements, or understood for how lengthy and just how widely it was being made use of throughout the nation," claims Mueller. After discussions at the technical meeting, he says, "It quickly went from being simply an issue in Illinois to becoming a nationwide and worldwide issue." Part of the objective of the Chemistry Research Laboratory at TFHRC is to develop new test techniques.
