Materiaaltesten Fundering Standard Rotational Viscometer
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.
Rotary viscometer matches ASTM D2196, ASTM D4402 and AASTHO T316 requirements.
