The DSR enables item designers to develop tooth paste with the best consistency so that it can be squeezed from a tube however not drop off the tooth brush. The DSR tests binder put between two identical plates regarding the size of a quarter. One of the plates relocations and the maker measures the viscoelastic buildings of the asphalt.
