The machine was not developed for the paving industry (https://linktr.ee/a1asphaltseal).


As an example, the DSR enables item designers to create tooth paste with the right uniformity so that it can be squeezed from a tube but not fall off the toothbrush. The from this source DSR tests binder placed between 2 identical plates concerning the size of a quarter. One of the plates relocations and the machine determines the viscoelastic homes of the asphalt.
