For example, the DSR allows product developers to create tooth paste with the ideal consistency so that it can be squeezed from a tube but not drop off the toothbrush. The DSR tests binder positioned between two identical plates concerning the size of a quarter. Among home plates relocations and the machine gauges the viscoelastic properties of the asphalt.
