The DSR allows product designers to create tooth paste with the appropriate consistency so that it can be pressed from a tube but not fall off the toothbrush. The DSR tests binder positioned in between two identical plates regarding the dimension of a quarter. Among the plates actions and the equipment determines the viscoelastic residential properties of the asphalt.
