It has actually been made use of in leading for more than a a century.

Today, nevertheless, it is an extremely traded product that requires premium costs. These costs have enhanced considerably. In 2002, asphalt cost around $160 per bunch.

The supplier refuted adding PPA, however decreased to reveal what had actually been added to the binder. When pushed by the division of transportation, the vendor revealed that it was adding what it called an asphalt extendernow known to be re-refined engine oil bottoms (REOB).
