As an example, the DSR enables item programmers to develop tooth paste with the right consistency to ensure that it can be squeezed from a tube but not diminish the toothbrush. The DSR tests binder placed in between 2 identical plates about the size of a quarter. One of home plates actions and the equipment determines the viscoelastic residential properties of the asphalt.
