Viscosity

81-B0120/B with thermometer
Viscosity corresponds to the resistance of a liquid to flowing, so it’s a parameter strictly related to binder consistency and workability. Binder viscosity is heavily affected by temperature, and is measured using different methods such as measuring the time needed to pass through a capillary (kinematic and dynamic viscosity), an orifice (Standard TAR, Engler and Saybolt viscosity) or the force needed to rotate two coaxial cylinders (Rotational viscometer).

Dynamic Viscometers

For determining the dynamic viscosity with Cannon-Manning and AI viscometers.

Standards ASTM D2171 EN 12596

81-B0117/1 to 81-B0117/11
Description

 

Cannon-Manning  and Asphalt Institute vacuum viscometers
Used for determining the viscosity of bitumen at 60°C. Supplied complete with calibration certificate.
 
For determining the dynamic viscosity all the above viscometers have to be introduced in the 81-B0116/A Viscometer bath by the appropriate Holder: 81-B0117/H1 for Cannon-Manning models and 81-B0117/H2 for Asphalt institute models. Pressure regulator and vacuum manifold is also required. See accessories.

 

Viscometer bath is used in the determination of both the kinematic and dynamic viscosity. Used to maintain the
capillary type viscometers at a uniform temperature. The bath consists of a cylindrical glass vessel with a stainless steel cover with 50.8 mm diameter holes, motor stirrer, refrigerating coil with water connections, heating system, contact thermometer, external protection and insulating base.
