When pushed by the department of transportation, the supplier exposed that it was adding what it called an asphalt extendernow recognized to be re-refined engine oil bottoms (REOB). REOB includes a percentage of phosphorus, which is what department drug stores at first identified.


"No person understood this material was being contributed to asphalt, had seen any kind of research study on how this could impact performance of hot-mix view asphalt sidewalks, or understood for how much time and exactly how widely it was being used throughout the nation," says Mueller. After conversations at the technological meeting, he says, "It quickly went from being simply a concern in Illinois to becoming a nationwide and global concern."
