The DSR makes it possible for item programmers to produce toothpaste with the ideal consistency so that it can be squeezed from a tube however not fall off the toothbrush. The DSR tests binder positioned in between 2 identical plates regarding the dimension of a quarter. Among the plates actions and the equipment measures the viscoelastic residential properties of the asphalt.
