Nonetheless, the equipment was not established for the paving market.


The DSR makes it possible for item programmers to produce toothpaste with the right uniformity so that it can be squeezed from a tube but not drop off the tooth brush. The DSR tests binder positioned in between two parallel plates about the size of a quarter. Among home plates relocations and the machine gauges the viscoelastic properties of the asphalt.
