As an example, the DSR enables item designers to develop tooth paste with the ideal uniformity so that it can be pressed from a tube but not diminish the tooth brush. The DSR examinations binder placed between two identical plates about the dimension of a quarter. One of the plates steps and the machine measures the viscoelastic residential properties of the asphalt.
