The device was not developed for the paving industry (https://trello.com/w/a1asphaltseal_).


The DSR allows product designers to create toothpaste with the right consistency so that it can be squeezed from a tube but not drop off the toothbrush. The DSR tests binder positioned between 2 identical plates about the size of a quarter. Among the plates relocations and the machine measures the viscoelastic residential properties of the asphalt.
