For example, the DSR allows item designers to create tooth paste with the ideal consistency so that it can be squeezed from a tube but not fall off the tooth brush. The DSR examinations binder put in between 2 parallel plates concerning the size of a quarter. Among the plates moves and the equipment determines the viscoelastic buildings of the asphalt.
