The DSR makes it possible for item designers to create tooth paste with the ideal consistency so that it can be pressed from a tube yet not fall off the toothbrush. The DSR tests binder positioned between 2 identical plates about the size of a quarter. One of home plates relocations and the maker measures the viscoelastic properties of the asphalt.
