The maker was not created for the paving market (https://www.pinterest.com/pin/1032942865763323640).


The DSR allows item designers to create tooth paste with the right consistency so that it can be squeezed from a tube yet not drop off the tooth brush. The DSR tests binder put in between 2 identical plates concerning the dimension of a quarter. One of the plates actions and the maker measures the viscoelastic properties of the asphalt.
