For example, the DSR makes it possible for item developers to develop tooth paste with the appropriate uniformity to ensure that it can be pressed from a tube but not fall off the tooth brush. The DSR tests binder placed in between two parallel plates regarding the dimension of a quarter. One of home plates steps and the equipment determines the viscoelastic homes of the asphalt.
