Dynamic Shear Rheometers are configured to meet the demands of everyday quality control testing of 4, 8, and 18mm samples in asphalt production facilities. These models are ideal for the classification of SHRP/Superpave PG binders.

A disc-shaped binder sample is confined between two parallel plates and subjected to horizontal oscillation to determine dynamic shear properties. The synchronous, brushless DC motor drives a rotor mounted on a frictionless air bearing to allow the most precise movement and sensitive measurements. An operation requires a clean, dry, and oil-free supply of compressed air.
