For instance, the DSR allows item designers to produce tooth paste with the ideal uniformity so that it can be squeezed from a tube however not diminish the tooth brush. The DSR examinations binder positioned between 2 parallel plates regarding the dimension of a quarter. One of the plates moves and the machine determines the viscoelastic properties of the asphalt.
