An equipment called a vibrant shear rheometer (DSR) was presented to the market during the Strategic Highway Research Program's study task, which ranged from 1987 to 1992.

For instance, the DSR allows product developers to create tooth paste with the appropriate uniformity to ensure that it can be squeezed from a tube but not diminish the tooth brush. The DSR tests binder placed in between 2 parallel plates regarding the size of a quarter. Among the plates moves and the equipment determines the viscoelastic residential properties of the asphalt.
