The supplier rejected including PPA, but declined to expose what had been included to the binder. When pressed by the department 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 has a percentage of phosphorus, which is what division chemists initially identified.


"No one understood this product was being included to asphalt, had seen any research on exactly how this may influence efficiency of hot-mix asphalt sidewalks, or recognized for the length of time and just how commonly it was being utilized throughout the nation," says Mueller.

For instance, the DSR allows product designers to produce toothpaste with the best uniformity to make sure that it can be pressed from a tube but not diminish the tooth brush. The DSR examinations binder placed between two identical plates concerning the size of a quarter. One of home plates moves and the machine determines the viscoelastic properties of the asphalt.
