The equipment was not established for the paving market (https://zzri1z2o90l.typeform.com/to/BPqH2MM1).


The DSR makes it possible for item designers to produce tooth paste with the ideal consistency so that it can be pressed from here a tube but not drop off the tooth brush. The DSR tests binder placed in between 2 parallel plates about the dimension of a quarter. Among the plates moves and the machine measures the viscoelastic residential or commercial properties of the asphalt.
