A machine called a vibrant shear rheometer (DSR) was introduced to the market during the Strategic Highway Research Program's research task, which ran from 1987 to 1992. The DSR is currently the sector criterion for determining the viscoelastic residential or commercial properties of leading asphalt. However, the machine was not developed for the paving sector.


The DSR makes it possible for product designers to develop toothpaste with the best consistency so that it can be squeezed from a tube yet not fall off the tooth brush. The DSR tests binder positioned in between 2 parallel plates about the dimension of a quarter. One of the plates moves and the device determines the viscoelastic residential or commercial properties of the asphalt.
