Viscosity is resistance to flow caused by internal friction of a fluid. The rotational viscometer senses torque required to rotate a spindle at constant speed while immersed in the sample fluid. Dynamic viscosity is proportional to this measured torque. At the asphalt plant field lab, the rotational method gives a rapid and reproductible measurement of high temperature viscosity which correlates closely with the more traditional, but time-consuming, glass capillary viscometer method.
