A machine called a vibrant shear rheometer (DSR) was introduced to the industry throughout the Strategic Highway Research study Program's research task, which ranged from 1987 to 1992. The DSR is currently the market standard for measuring the viscoelastic homes of paving asphalt. The device was not developed for the paving sector (https://a1professionalasphaltandsealin.godaddysites.com/f/a1-professional-asphalt-sealing-llc-expert-asphalt-repairs-an).
