When pushed by the department of transportation, the vendor exposed that it was including what it called an asphalt extendernow understood to be re-refined engine oil bottoms (REOB). REOB has a small quantity of phosphorus, which is what division drug stores originally recognized.


"Nobody understood this material was being included in asphalt, had actually seen any kind of research study on how this might affect efficiency of hot-mix asphalt sidewalks, or understood for for how long and how extensively it was being used throughout the country," states Mueller. After discussions at the technological meeting, he says, "It rapidly went from being simply a problem in Illinois to ending up being a national and global worry."
