When pushed by the division of transportation, 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 percentage of phosphorus, which is what division chemists initially identified.


"No person recognized this material was being added to asphalt, had actually seen any type of research study on how this could impact efficiency of hot-mix asphalt sidewalks, or knew for how much time and exactly how widely it was being utilized throughout the nation," says Mueller. After discussions at the technological conference, he states, "It promptly went from being just a concern in Illinois to coming to be a national and international worry." Component of the objective of the Chemistry Lab at TFHRC is to develop brand-new examination approaches.
