The supplier refuted adding PPA, yet declined to reveal what had actually been added to the binder. When pressed by the department of transportation, the supplier disclosed that it was adding what it called an asphalt extendernow understood to be re-refined engine oil bases (REOB). REOB has a little quantity of phosphorus, which is what division chemists at first identified.


"Nobody understood this product was being included in asphalt, had actually seen any kind of research on just how this could affect performance of hot-mix asphalt sidewalks, or knew for the length of time and how commonly it was being made use of throughout the nation," says Mueller. After conversations at the technological conference, he says, "It promptly went from being simply a concern in Illinois to ending up being a nationwide and worldwide concern."

The DSR allows product developers to develop toothpaste with the right uniformity so that it can be squeezed from a tube but not drop off the tooth brush. The DSR tests binder positioned in between two identical plates regarding the size of a quarter. Among home plates moves and the equipment determines the viscoelastic residential properties of the asphalt.
