The equipment was not developed for the paving sector (https://johns-dynamite-site-e5d7b3.webflow.io/).


The DSR makes it possible for see this item designers to create toothpaste with the best uniformity so that it can be pressed from a tube yet not fall off the toothbrush. The DSR examinations binder put between 2 parallel plates regarding the dimension of a quarter. Among home plates moves and the machine determines the viscoelastic residential or commercial properties of the asphalt.
