As an example, the DSR allows product developers to develop tooth paste with the appropriate consistency so that it can be pressed from a tube however not diminish the toothbrush. The DSR tests binder positioned in between 2 parallel plates concerning the dimension of a quarter. Among the plates steps and the equipment measures the viscoelastic properties of the asphalt.
