A machine called a vibrant shear rheometer (DSR) was introduced to the sector during the Strategic Freeway Study Program's study project, which ran from 1987 to 1992. The DSR is currently the market standard for gauging the viscoelastic residential or commercial properties of leading asphalt. The device was not developed for the paving industry (https://qualtricsxm4qwdsn59g.qualtrics.com/jfe/form/SV_0H8SwRAI7gGMMQK).


The DSR allows item programmers to produce tooth paste with the right consistency so that it can be pressed from a tube yet not fall off the tooth brush. The DSR tests binder placed in between two identical plates about the size of a quarter. One of the plates steps and the maker determines the viscoelastic residential or commercial properties of the asphalt.
