As an example, the DSR allows product developers to develop tooth paste with the ideal consistency to make sure that it can be squeezed from a tube but not fall off the tooth brush. The DSR examinations binder put between two identical plates concerning the dimension of a quarter. One of home plates moves and the device determines the viscoelastic properties of the asphalt.
