The supplier refuted including PPA, yet declined to reveal what had been included in the binder. When pressed by the division of transportation, the supplier revealed that it was adding 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 division chemists at first determined.


"No one knew this product was being contributed to asphalt, had seen any research on just how this might influence performance of hot-mix asphalt sidewalks, or knew for the length of time and exactly how widely it was being made use of throughout the country," says Mueller. After conversations at the technical conference, he states, "It promptly went from being simply a problem in Illinois to becoming a national and global concern." Part of the objective of the Chemistry Laboratory at TFHRC is to develop new test approaches.


The buildings of asphalt binders vary widely relying on the resource of the unrefined oil and the refining procedure used.

The DSR examinations binder positioned between two identical plates concerning the size of a quarter. Among home plates moves and the equipment gauges the viscoelastic residential or commercial properties of the asphalt.
