The vendor denied adding PPA, yet decreased to expose what had actually been included in the binder. When pressed by the division of transport, the vendor disclosed that it was including what it called an asphalt extendernow recognized to be re-refined important source engine oil bases (REOB). REOB consists of a tiny amount of phosphorus, which is what division chemists initially identified.


"Nobody understood this product was being contributed to asphalt, had seen any kind of research study on how this could impact performance of hot-mix asphalt sidewalks, or recognized for for how long and exactly how extensively it was being utilized throughout the country," states Mueller. After conversations at the technical meeting, he states, "It rapidly went from being simply an issue in Illinois to becoming a national and international concern."

The DSR enables item programmers to create tooth paste with the appropriate consistency so that it can be pressed from a tube yet not fall off the toothbrush. The DSR tests binder put in between two identical plates about the size of a quarter. One of home plates relocations and the device gauges the viscoelastic properties of the asphalt.
