The equipment was not established for the paving sector (https://www.quora.com/profile/John-Tally-19).


The DSR enables product developers to develop toothpaste with the appropriate uniformity so that it can be squeezed from a tube but not fall off the toothbrush. The DSR tests binder placed in between 2 identical plates about the dimension of a quarter. Among home plates moves and the maker gauges the viscoelastic properties of the asphalt.
