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


The DSR makes it possible for item programmers to create toothpaste with the ideal uniformity so that it can be pressed from a tube but not drop off the toothbrush. The DSR tests binder placed between 2 parallel plates concerning the size of a quarter. One of the plates actions and the machine determines the viscoelastic properties of the asphalt.
