It has been utilized in leading for greater than a a century.


Today, nevertheless, it is an extremely traded product that demands premium costs. These costs have actually boosted dramatically. In 2002, asphalt cost approximately $160 per load. By the end of 2006, the cost had doubled to approximately $320 per load, and afterwards it almost doubled once more in 2012 to about $610 per ton.

The vendor denied including PPA, however declined to disclose what had been included to the binder. When pushed by the division of transport, the supplier exposed that it was adding what it called an asphalt extendernow known to be re-refined engine oil bottoms (REOB).

A maker called a dynamic shear rheometer (DSR) was introduced to the industry throughout the Strategic Freeway Study Program's study job, which ranged from 1987 to 1992. The DSR is now the industry standard for gauging the viscoelastic homes of paving asphalt. However, the device was not developed for the paving industry.


The DSR allows item developers to produce tooth paste with the appropriate uniformity so that it can be pressed from a tube however not drop off the toothbrush. The DSR examinations binder positioned in between two identical plates regarding the size of a quarter. One of the plates actions and the machine gauges the viscoelastic homes of the asphalt.
