It has been made use of in leading for more than a hundred years.

Today, however, it is a highly traded commodity that demands premium prices. These prices have enhanced dramatically. In 2002, asphalt offered for around $160 per bunch.

The vendor refuted including PPA, yet decreased to disclose what had been added to the binder. When pressed by the division of transportation, the supplier exposed that it was including what it called an asphalt extendernow understood to be re-refined engine oil bases (REOB). REOB has a small quantity of phosphorus, which is what division drug stores at first determined.

"No person recognized this material was being contributed to asphalt, had actually seen any kind of research study on how this could impact performance of hot-mix asphalt sidewalks, or knew for the length of time and how extensively it was being utilized throughout the nation," says Mueller.
