A device called a vibrant shear rheometer (DSR) was presented to the sector during the Strategic Freeway Research Program's study project, which ran from 1987 to 1992. The DSR is now the sector standard for determining the viscoelastic residential properties of paving asphalt. The equipment was not established for the paving sector (https://hub.docker.com/u/a1asphaltseal).


The DSR enables product developers to develop tooth paste with the best consistency so that it can be pressed from a tube however not fall off the tooth brush. The DSR examinations binder placed in between 2 parallel plates next about the dimension of a quarter. Among the plates actions and the machine gauges the viscoelastic buildings of the asphalt.
