The vendor refuted including PPA, however declined to expose what had been added to the binder. When pressed by the division of transport, the vendor exposed that it was adding what it called an asphalt extendernow recognized to be re-refined engine oil bases (REOB). REOB consists of a small amount of phosphorus, which is what department drug stores at first identified.


"No person understood this material was being included in asphalt, had seen any research study on how this might affect efficiency of hot-mix asphalt sidewalks, or understood for the length of time and just how extensively it was being utilized throughout the country," claims Mueller. After conversations at the technical conference, he says, "It quickly went from being just an issue in Illinois to coming to be a national and global problem." Component of the objective of the Chemistry Laboratory at TFHRC is to create new test approaches.

One of the plates actions and the maker measures the viscoelastic residential or commercial properties of the asphalt.
