The DSR more info here is now the industry standard for gauging the viscoelastic properties of leading asphalt. However, the device was not developed for the paving market.


The DSR allows product programmers to create toothpaste with the right uniformity so that it can be squeezed from a tube yet not fall off the tooth brush. The DSR examinations binder positioned 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.
