A device called a dynamic shear rheometer Continued (DSR) was introduced to the industry during the Strategic Highway Research study Program's research study job, which ran from 1987 to 1992. The DSR is now the market standard for gauging the viscoelastic homes of paving asphalt. The device was not developed for the paving market (https://www.storeboard.com/a1professionalasphaltandsealingllc).
