Description

Apparent viscosity of unfilled asphalt is evaluated by a rotational viscometer  which measures the torque generated by a calibrated spindle rotating at a selected speed into a bitumen sample heated at  precise temperature in the range between ambient temperature to 260°C. The measured relative resistance to rotation is converted, by a factor,  in viscosity units, cP or mPa·s.
