Matest GyroResearch – Gyratory compactor


Used for research purposes, this electromechanical compactor allows for adjusting the gyratory angle, selectable in a range between 0° and 3°, during compaction, real-time direct shear, and torque measurement.

It is one of the required equipment for volumetric mix design, The Superpave method defines the mechanism of mix compaction using this method.
