An equipment called a dynamic shear rheometer (DSR) was introduced to the industry during the Strategic Highway Research Program's research project, which ranged from 1987 to 1992. The DSR is currently the sector standard for measuring the viscoelastic homes of see here now paving asphalt. Nevertheless, the device was not created for the paving market.


For example, the DSR allows item programmers to develop tooth paste with the best uniformity to ensure that it can be squeezed from a tube however not diminish the toothbrush. The DSR tests binder put between two parallel plates concerning the dimension of a quarter. One of the plates actions and the equipment determines the viscoelastic residential properties of the asphalt.
