The supplier rejected including PPA, however decreased to disclose what had actually been included in the binder. When pressed by the division of transport, the supplier disclosed that it was including what it called an asphalt extendernow understood to be re-refined engine oil bottoms (REOB). REOB has a small quantity of phosphorus, which is what department chemists initially determined.


"No person knew this product was being included in asphalt, had seen any research on how this might impact performance of hot-mix asphalt pavements, or understood for for how long and exactly how extensively it was being utilized throughout the country," claims Mueller. After discussions at the technological conference, he says, "It quickly went from being simply a problem in Illinois to becoming a nationwide and global issue." Part of the mission of the Chemistry Laboratory at TFHRC is to create site here new test approaches.

The DSR allows product developers to produce tooth paste with the right uniformity so that it can be squeezed from a tube yet not drop off the toothbrush. The DSR tests binder positioned in between two parallel plates concerning the dimension of a quarter. Among the plates relocations and the device measures the viscoelastic homes of the asphalt.
