For instance, the DSR makes it possible for item programmers to develop tooth paste with the ideal uniformity to make sure that it can be pressed from a tube but not diminish the tooth brush. The DSR tests binder placed between 2 parallel plates about the size of a quarter. Among home plates steps and the equipment measures the viscoelastic properties of the asphalt.
