In 2002, asphalt offered for around $160 per heap. a-1 asphalt. By the end of 2006, the expense had doubled to roughly $320 per load, and after that it nearly doubled once again in 2012 to about $610 per load.

A maker called a vibrant shear rheometer (DSR) was introduced to the industry during the Strategic Freeway Study Program's research project, which ranged from 1987 to 1992.

The DSR enables product developers to create toothpaste with the right uniformity so that it can be squeezed from a tube yet not drop off the tooth brush. The DSR examinations binder put in between 2 parallel plates about the dimension of a quarter. One of home plates relocations and the machine gauges the viscoelastic homes of the asphalt.
