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 precise temperature in the range from ambient temperature to 260° C. The measured relative resistance to rotation is converted, with a factor, in viscosity units, cP or mPa·s.

Accessories

The temperature control unit consist of a heating chamber that is used to work in conjunction with rotary viscometers at high temperatures. Viscosity of solid road unfilled asphalts has to be measured at temperatures ranging from 34°C to 260° according to the Specifications of ASTM D4402. The heater contains the container with sample in which a suitable spindle is immersed and driven by the rotary viscometer to measure viscosity. A digital microprocessor control unit grants the required accuracy of test temperature.
