For instance, the DSR allows product programmers to develop toothpaste with the best uniformity so that it can be squeezed from a tube but not fall off the toothbrush. The DSR tests binder positioned in between two parallel plates regarding the dimension of a quarter. One of home plates steps and the machine measures the viscoelastic properties of the asphalt.
