The DSR allows product developers to create tooth paste with the best consistency so that it can be squeezed from a tube but not fall off the tooth brush. The DSR tests binder positioned between 2 identical plates regarding the dimension of a quarter. Among the plates moves and the maker determines the viscoelastic residential or commercial properties of the asphalt.
