The DSR makes it possible for item developers to create tooth paste with the ideal consistency so that it can be pressed from a tube but not drop off the tooth brush. The DSR examinations binder positioned in between 2 identical plates concerning the size of a quarter. One of home plates moves and the device measures the viscoelastic properties of the asphalt.
