A machine called a vibrant shear rheometer (DSR) was introduced to the industry throughout the Strategic Freeway Study Program's study job, which ran from 1987 to 1992. The DSR is currently the market requirement for measuring the viscoelastic residential properties of paving asphalt. However, the machine was not created for the paving market.


The DSR makes it possible for product developers to develop toothpaste with the appropriate uniformity so that it can be squeezed from a tube however not fall off the tooth brush.
