A device called a dynamic shear rheometer (DSR) was presented to the market throughout the Strategic Highway Study Program's study project, which ran from 1987 to 1992. The DSR is now the market criterion for determining the viscoelastic properties of paving asphalt. The equipment was not developed for the paving market (https://on.soundcloud.com/zC6fEriMVi1B9q7z8).


The DSR allows product designers to create tooth paste with the best consistency so that it can be pressed from a tube yet not drop off the tooth brush. The DSR examinations binder placed in between 2 identical plates regarding the size of a quarter. One of the plates relocations and the maker determines the viscoelastic homes of the asphalt.
