The supplier denied including PPA, but decreased to disclose what had been contributed to the binder. When pressed by the division of transport, the vendor disclosed that it was including what it called an asphalt extendernow understood to be re-refined engine oil bottoms (REOB). REOB includes a percentage of phosphorus, which is what division chemists initially recognized.


"No person knew this material was being added to asphalt, had actually seen any research on how this might impact performance of hot-mix asphalt sidewalks, or recognized for the length of time and how widely it was being made use of throughout the nation," claims Mueller. After conversations at the technological meeting, he says, "It quickly went from being simply a concern in Illinois to coming to be a nationwide and worldwide worry."

A maker called a vibrant shear rheometer (DSR) was introduced to the market during the Strategic Highway Research Program's study project, which ran from 1987 to 1992. The DSR is currently the industry standard for gauging the viscoelastic properties of paving asphalt. The machine was not established for the paving market (https://www.indiegogo.com/individuals/37631252).


The DSR allows product programmers to produce toothpaste with the ideal uniformity so that it can be pressed from a tube but not fall off the toothbrush.
