The supplier denied including PPA, yet decreased to reveal what had actually been contributed to the binder. When pushed 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 percentage of phosphorus, which is what department chemists initially recognized.


"No person recognized this product was being contributed to asphalt, had seen any research on how this might impact efficiency of hot-mix asphalt sidewalks, or recognized for how much time and just how commonly it was being made use of throughout the country," says Mueller. After conversations at the technological conference, he claims, "It rapidly went from being simply an issue in Illinois to becoming a nationwide and global worry."

For instance, the DSR makes it possible for product developers to produce tooth paste with the best consistency to ensure that it can be squeezed from a tube but not diminish the toothbrush. The DSR examinations binder positioned between two identical plates concerning the dimension of a quarter. One of home plates actions and the machine gauges the viscoelastic properties of the asphalt.
