Rotational Viscometers
Standard Rotational Viscometer
Used to measure the apparent viscosity of a binder.
Standards ASTM D4402 AASHTO T316 EN 13302 ASTM D2196
Rotational viscometer 81-PV0118/C
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.
