The DSR allows product developers to create tooth paste with the ideal uniformity so that it can be squeezed from a tube but not fall off the tooth brush. The DSR examinations binder put in between 2 parallel plates regarding the size of a quarter. One of home plates steps and the machine gauges the viscoelastic residential properties of the asphalt.
