An equipment called a vibrant shear rheometer (DSR) was introduced to the market during the Strategic Freeway Research study Program's research job, which ran from 1987 to 1992. The DSR is now the market requirement for gauging the viscoelastic buildings of leading asphalt. Nonetheless, the equipment was not developed for the paving market.


As an example, the DSR allows item designers to produce toothpaste with the ideal consistency so that it can be squeezed from a tube yet not fall off the toothbrush. The DSR tests binder placed in between two parallel plates regarding the dimension of a quarter. One of home plates moves and the device determines the viscoelastic properties of the asphalt.
