The vendor refuted including PPA, yet declined to reveal what had actually been contributed to the binder. When pushed by the division of transport, the vendor revealed that it was adding what it called an asphalt extendernow recognized to be re-refined engine oil bases (REOB). REOB has a small amount of phosphorus, which is what department chemists initially determined.


"No person recognized this material was being included in asphalt, had actually seen any kind of study on just how this could influence efficiency of hot-mix asphalt sidewalks, or knew for for how long and how widely it was being used throughout the nation," states Mueller. After discussions like this at the technical conference, he says, "It swiftly went from being just an issue in Illinois to becoming a nationwide and global worry."

A device called a dynamic shear rheometer (DSR) was introduced to the sector during the Strategic Highway Research study Program's research study job, which ran from 1987 to 1992.
