A machine called a dynamic shear rheometer (DSR) was introduced to the industry throughout the Strategic Highway Research Program's research study project, which ran from 1987 to 1992. The DSR is currently the market criterion for measuring the viscoelastic properties of leading asphalt. The maker was not developed for the paving industry (https://www.intensedebate.com/people/a1asphaltseal).


For instance, the DSR enables product developers to create tooth paste with the best consistency so that it can be pressed from a tube yet not diminish the tooth brush. The DSR tests binder placed in between 2 identical plates about the size of a quarter. Among home plates actions and the machine measures the viscoelastic properties of the asphalt.
