"No person understood this product was being included to asphalt, had seen any kind of research study on exactly how this might influence efficiency of hot-mix asphalt pavements, or understood for the length of time and exactly how extensively it was being utilized throughout the nation," claims Mueller.

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