The supplier refuted adding PPA, however declined to reveal what had actually been added to the binder. When pressed by the division of transportation, the supplier revealed that it was adding what it called an asphalt extendernow known to be re-refined engine oil bases (REOB). REOB has a tiny amount of phosphorus, which is what department drug stores initially recognized.


"No person recognized this material was being included to asphalt, had seen any type of study on just how this may affect efficiency of hot-mix asphalt pavements, or recognized for how much time and how extensively it was being utilized throughout the nation," says Mueller. After conversations at the technical meeting, he claims, "It quickly went from being simply a concern in Illinois to becoming a nationwide and global problem."

For example, the DSR enables product developers to develop tooth paste with the best consistency to make sure that it can be pressed from a tube however not diminish the tooth brush. The DSR examinations binder put between 2 parallel plates concerning the dimension of a quarter. One of home plates moves and the equipment determines the viscoelastic homes of the asphalt.
