The DSR allows item developers to create toothpaste with the appropriate uniformity so that it can be squeezed from a tube but not drop off the toothbrush. The DSR tests binder positioned between 2 parallel plates concerning the dimension of a quarter. Among the plates moves and the machine determines the viscoelastic properties of the asphalt.
