The supplier refuted including PPA, however decreased to expose what had been included in the binder. When pushed by the division of transport, the vendor disclosed that it was including what it called an asphalt extendernow known to be re-refined engine oil bottoms (REOB). REOB includes a percentage of phosphorus, which is what division chemists at first recognized.


"No one recognized this material was being added to asphalt, had actually seen any type of research on exactly how this may impact performance of hot-mix asphalt sidewalks, or knew for how much time and exactly how extensively it was being utilized throughout the nation," says Mueller. After discussions at the technological conference, he states, "It rapidly went from being simply a problem in Illinois to becoming a nationwide and international problem." Part of the objective of the Chemistry Laboratory at TFHRC is to create new examination techniques.
