The vendor denied adding PPA, but decreased to expose what had actually been contributed to the binder. When pushed by the division of transportation, the supplier disclosed that it was adding what it called an asphalt extendernow recognized to be re-refined engine oil bottoms (REOB). REOB includes a small quantity of phosphorus, which is what division drug stores originally identified.


"Nobody understood this material was being included to asphalt, had seen any type of research on exactly how this may affect performance of hot-mix asphalt pavements, or knew for how much time and how commonly it was being made use of throughout the nation," states Mueller. After conversations at the technological conference, he says, "It swiftly went from being simply a concern in Illinois to ending up being a nationwide and global issue."

As an example, the DSR makes it possible for item programmers to produce toothpaste with the ideal uniformity to ensure that it can be pressed from a tube but not fall off the toothbrush. The DSR tests binder put in between 2 parallel plates regarding the size of a quarter. Among the plates relocations and the equipment gauges the viscoelastic properties of the asphalt.
