Standard Rotational Viscometer

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. 

Rotary viscometer matches ASTM D2196, ASTM D4402 and AASTHO T316 requirements.
