The vendor refuted including PPA, yet declined to disclose what had been contributed to the binder. When pressed by the department of transport, the supplier revealed that it was adding what it called an asphalt extendernow known to be re-refined engine oil bases (REOB). REOB consists of a percentage of phosphorus, which is what department chemists at first identified.


"Nobody understood this product was being included in asphalt, had actually seen any kind of research on just how this may impact efficiency of hot-mix asphalt sidewalks, or recognized for how long and exactly how extensively it was being used throughout the country," says Mueller. After discussions at the technological conference, he claims, "It quickly went from being simply a problem in Illinois to coming to be a national and global worry."

For instance, the DSR enables item designers to produce toothpaste with the right uniformity to make sure that it can be pressed from a tube however not diminish the toothbrush. The DSR tests binder placed in between 2 identical plates about the size of a quarter. Among the plates moves and the machine gauges the viscoelastic properties of the asphalt.
