An equipment called a vibrant shear rheometer (DSR) was presented to the market during the Strategic Freeway Research Program's research job, which ran from 1987 to 1992.

The device was not developed for the paving sector (https://medium.com/@a1asphaltsealng/about).


The DSR enables product programmers to develop toothpaste with the right uniformity so that it can be pressed from a tube but not drop off the toothbrush. The DSR tests binder positioned in between two parallel plates concerning the dimension of a quarter. One of the plates actions and the equipment determines the viscoelastic residential properties of the asphalt.
