"No person recognized this product was being included in asphalt, had seen any type of research on how this could influence performance of hot-mix asphalt pavements, or recognized for the length of time and just how commonly it was being used throughout the nation," states Mueller. After discussions at the technological conference, he states, "It quickly went from being simply a concern in Illinois to becoming a nationwide and international worry."

An equipment called a dynamic shear rheometer (DSR) was presented to the market during the Strategic Freeway Research study Program's research project, which ranged from 1987 to 1992. The DSR is now the industry criterion for measuring the viscoelastic buildings of paving asphalt. The device was not created for the paving market (https://www.blogtalkradio.com/a1asphaltsealng).


The DSR enables item designers to create tooth paste with the right uniformity so that it can be squeezed from a tube yet not fall off the tooth brush. The DSR tests binder put between two identical plates about the dimension of a quarter. One of home plates moves and the equipment measures the viscoelastic properties of the asphalt.
