The supplier denied adding PPA, yet declined to reveal what had been included in the binder. When pushed by the department of transportation, the vendor disclosed that it was including what it called an asphalt extendernow understood to be re-refined engine oil bottoms (REOB). REOB has a tiny amount of phosphorus, which is what department drug stores initially identified.


"No person understood this material was being contributed to asphalt, had actually seen any research study on just how this may influence performance of hot-mix asphalt pavements, or knew for just how long and how commonly it was being used throughout the country," claims Mueller. After discussions at the technological meeting, he states, "It swiftly went from being simply an issue in Illinois to coming to be a nationwide and worldwide problem."

As an example, the DSR allows product programmers to produce toothpaste with the right uniformity to make sure that it can be squeezed from a tube but not fall off the toothbrush. The DSR examinations binder positioned in between 2 identical plates about the size of a quarter. Among home plates actions and the device determines the viscoelastic properties of the asphalt.
