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 tooth brush. The DSR tests binder positioned in between 2 parallel plates about the dimension of a quarter. One of the plates moves and the machine measures the viscoelastic properties of the asphalt.
