It has actually been used in paving for greater than a a century.


Today, nonetheless, it is an extremely traded asset that requires costs costs. These prices have actually enhanced drastically. In 2002, asphalt cost about $160 per load. By the end of 2006, the cost had actually increased to about $320 per ton, and after that it nearly doubled once more in 2012 to about $610 per load.

The vendor refuted adding PPA, yet declined to expose what had actually been included in the binder. When pressed by the division of transport, the supplier exposed that it was including what it called an asphalt extendernow known to be re-refined engine oil bottoms (REOB). REOB includes a percentage of phosphorus, which is what department chemists initially recognized.


"No person knew this product was being added to asphalt, had seen any type of research on exactly how this might affect performance of hot-mix asphalt pavements, or knew for how long and just how commonly it was being utilized throughout the nation," states Mueller. After conversations at the technological conference, he states, "It quickly went from being simply an issue in Illinois to ending up being a nationwide and worldwide issue."
