Today, however, it is a highly traded commodity that demands premium prices. These prices have boosted dramatically. In 2002, asphalt sold for approximately $160 per load. By the end of 2006, the expense had doubled to roughly $320 per lot, and after that it practically doubled once again in 2012 to approximately $610 per heap.

The supplier refuted including PPA, yet decreased to expose what had been contributed to the binder. When pushed by the department of transportation, the vendor disclosed that it was adding what it called an asphalt extendernow recognized to be re-refined engine oil bottoms (REOB). REOB includes a percentage of phosphorus, which is what division chemists initially identified.


"No person understood this product was being included to asphalt, had seen any kind of study on exactly how this might affect efficiency of hot-mix asphalt pavements, or recognized for the length of time and just how extensively it was being utilized throughout the country," claims Mueller. After discussions at the technological meeting, he says, "It rapidly went from being simply an issue in Illinois to ending up being a national and global issue."

For instance, the DSR enables product developers to create tooth paste with the ideal uniformity to ensure that it can be squeezed from a tube but not diminish the tooth brush. The DSR tests binder positioned in between two parallel plates concerning the dimension of a quarter. Among the plates moves and the equipment determines the viscoelastic residential properties of the asphalt.
