"Nobody recognized this product was being contributed to asphalt, had actually seen any type of research on just how this may influence performance of hot-mix asphalt sidewalks, or understood for the length of time and how widely it was being used throughout the nation," says Mueller.

The DSR enables product programmers to develop toothpaste with the right consistency so that it can be squeezed from a tube yet not drop off the tooth brush. The DSR tests binder placed between 2 parallel plates concerning the dimension of a quarter. One of home plates steps and the equipment gauges the viscoelastic properties of the asphalt.
