As an example, the DSR allows item designers to create tooth paste with the ideal uniformity to ensure that it can be squeezed from a tube but not fall off the tooth brush. The DSR tests binder placed in between two parallel plates concerning the size of a quarter. Among home plates relocations and the machine measures the viscoelastic homes of the asphalt.
