As an example, the DSR makes it possible for item programmers to create toothpaste with the appropriate consistency to ensure that it can be squeezed from a tube however not diminish the tooth brush. The DSR tests binder put between two identical plates concerning the dimension of a quarter. One of the plates moves and the machine measures the viscoelastic properties of the asphalt.
