The machine was not established for the paving market (https://www.figma.com/file/yzsVUjKAAMwHaseBWJlaDs/Untitled?type=design&node-id=0%3A1&mode=design&t=xf2tw9x6SpbE0IGO-1).


The DSR enables product developers to develop tooth paste with the best uniformity so that it can be pressed from a tube however not drop off the tooth brush. The DSR examinations binder placed between two identical plates concerning the dimension of a quarter. Among home plates moves and the device measures the viscoelastic buildings of the asphalt.
