The DSR is currently the sector standard for gauging the viscoelastic homes of paving asphalt. However, the equipment was not established for the paving sector.


For example, the DSR makes it possible for product designers to develop toothpaste with the ideal consistency to make sure that it can be squeezed from a tube but not fall off the tooth brush. The DSR tests binder put in between two parallel plates about the dimension of a quarter. One of home plates moves and the maker measures the viscoelastic homes of the asphalt.
