The vendor refuted adding PPA, but declined to expose what had actually been included in the binder. When pushed by the division of transportation, the vendor exposed that it was adding what it called an asphalt extendernow known to be re-refined engine oil bottoms (REOB). REOB contains a small amount of phosphorus, which is what department chemists at first identified.


"Nobody recognized this product was being included in asphalt, had actually seen any kind of research study on just how this could impact performance of hot-mix asphalt pavements, or recognized for the length of time and just how commonly it was being utilized throughout the country," says Mueller. After discussions at the technological conference, he states, "It promptly went from being just an issue in Illinois to ending up being a nationwide and worldwide worry."

For instance, the DSR makes it possible for item programmers to develop tooth paste with the appropriate consistency to make sure that it can be squeezed from a tube but not drop off the toothbrush. The DSR tests binder positioned between two parallel plates concerning the size of a quarter. One of home plates actions and the device determines the viscoelastic properties of the asphalt.
