An equipment called a vibrant shear rheometer (DSR) was presented to the sector throughout the Strategic Freeway Study Program's research task, which ran from 1987 to 1992.

The equipment was not created for the paving industry (https://www.easel.ly/browserEasel/14465169).


The DSR allows item programmers to create toothpaste with the ideal consistency so that it can be squeezed from a tube however not drop off the tooth brush.
