The vendor denied including PPA, but declined to disclose what had been included in the binder. When pushed by the department of transportation, the vendor disclosed that it was including what it called an asphalt extendernow understood to be re-refined engine oil bases (REOB). REOB has a tiny quantity of phosphorus, which is what division chemists originally identified.


"Nobody understood this material was being contributed to asphalt, had actually seen any research on exactly how this might affect performance of hot-mix asphalt sidewalks, or understood for just how long and just how widely it was being utilized throughout the country," says Mueller. After discussions at the technological conference, he states, "It rapidly went from being just a problem in Illinois to ending up being a national and worldwide issue."

For example, the DSR enables product developers to create toothpaste with the right uniformity so that it can be pressed from a tube yet not fall off the toothbrush. The DSR examinations binder put between two identical plates concerning the dimension of a quarter. One of the plates relocations and the machine gauges the viscoelastic buildings of the asphalt.
