The vendor rejected adding PPA, but declined to disclose what had actually been included in the binder. When pushed by the division of transportation, the vendor revealed that it was including what it called an asphalt extendernow recognized to be re-refined engine oil bases (REOB). REOB contains a little amount of phosphorus, which is what department chemists originally recognized.


"Nobody understood this material was being included in asphalt, had seen any study on just how this could impact performance of hot-mix asphalt sidewalks, or recognized for for how long and exactly how widely it was being made use of throughout the nation," states Mueller. After discussions at the technological conference, he states, "It rapidly went from being just a concern in Illinois to ending up being a nationwide and worldwide issue."

A machine called a dynamic shear rheometer (DSR) was introduced to the market throughout the Strategic Freeway Research Program's research project, which ran from 1987 to 1992. The DSR is currently the market requirement for measuring the viscoelastic properties of leading asphalt. Nevertheless, the maker was not developed for the paving sector.


For instance, the DSR enables product developers to produce toothpaste with the ideal 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 parallel plates concerning the dimension of a quarter. One of the plates actions and the machine determines the viscoelastic residential properties of the asphalt.
