The DSR enables product programmers to develop tooth paste with the right consistency so that it can be squeezed from a tube but not drop off the toothbrush. The DSR tests binder placed between 2 parallel plates regarding the dimension of a quarter. Among the plates steps and the equipment gauges the viscoelastic buildings of the asphalt.
