For instance, the DSR makes it possible for item programmers to produce toothpaste with the right uniformity to make sure that it can be pressed from a tube however not diminish the tooth brush. The DSR tests binder placed in between 2 parallel plates about the dimension of a quarter. One of the plates relocations and the device measures the viscoelastic properties of the asphalt.
