For example, the DSR allows item programmers to develop toothpaste with the ideal uniformity to make sure that it can be squeezed from a tube but not diminish the tooth brush. The DSR tests binder positioned between 2 parallel plates about the dimension of a quarter. Among home plates actions and the machine determines the viscoelastic residential properties of the asphalt.
