GENERAL 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 a 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 requirements.
