The DSR allows product developers to produce toothpaste with the best consistency so that it can be squeezed from a tube yet not fall off the toothbrush. The DSR tests binder put in between two identical plates about the size of a quarter. One of the plates steps and the machine gauges the viscoelastic residential properties of the asphalt.
