For instance, the DSR enables product developers to develop tooth paste with the appropriate consistency to make sure that it can be squeezed from a tube but not diminish the toothbrush. The DSR tests binder positioned in between 2 parallel plates concerning the dimension of a quarter. One of the plates relocations and the device determines the viscoelastic residential properties of the asphalt.
