The supplier denied adding PPA, however decreased to reveal what had actually been contributed to the binder. When pushed by the division of transportation, the supplier exposed that it was including what it called an asphalt extendernow understood to be re-refined engine oil bases (REOB). REOB contains a percentage of phosphorus, which is what division chemists initially recognized.


"No one knew this product was being included in asphalt, had seen any research study on exactly how this could affect efficiency of hot-mix asphalt pavements, or knew for for how long and how commonly it was being utilized throughout the nation," claims Mueller. After discussions at the technological meeting, he says, "It rapidly went from being simply an issue in Illinois to becoming a nationwide and global worry." Part of the goal of the Chemistry Lab at TFHRC is to develop brand-new test techniques.

The DSR allows product designers to develop tooth paste with the right consistency so that it can be pressed from a tube however not fall off the toothbrush. The DSR tests binder put between 2 identical plates regarding the dimension of a quarter. Among home plates moves and the machine measures the viscoelastic homes of the asphalt.
