For instance, the DSR allows product designers to create toothpaste with the appropriate uniformity so that it can be squeezed from a tube but not diminish the toothbrush. The DSR tests binder placed between 2 identical plates about the dimension of a quarter. One of home plates moves and the machine gauges the viscoelastic properties of the asphalt.
