The vendor denied adding PPA, however decreased to disclose what had been contributed to the binder. When pressed by the department of transport, the supplier exposed that it was adding what it called an asphalt extendernow understood to be re-refined engine oil bases (REOB). REOB includes a percentage of phosphorus, which is what division drug stores initially recognized.


"No person recognized this product was being included in asphalt, had seen any type of study on how this might impact performance of hot-mix asphalt pavements, or recognized for for how long and just how extensively it was being utilized throughout the country," states Mueller. After conversations at the technical conference, he says, "It rapidly went from being just an issue in Illinois to ending up being a nationwide and international concern."

As an example, the DSR makes it possible for item developers to produce toothpaste with the best consistency to make sure that it can be squeezed from a tube however not diminish the toothbrush. The DSR tests binder placed in between two identical plates about the dimension of a quarter. One of home plates steps and the device gauges the viscoelastic homes of the asphalt.
