For example, the DSR allows item developers to develop toothpaste with the appropriate consistency to make sure that it can be squeezed from a tube but not diminish the toothbrush. The DSR tests binder placed between two identical plates regarding the dimension of a quarter. One of home plates moves and the equipment determines the viscoelastic residential properties of the asphalt.
