Gyratory compactors, used for the past twenty years all over the world, are the reference point in terms of user-friendliness combined with reliability and ergonomics, and they have been produced in hundreds of units. Gyratory technique basically consists in a compaction of a bituminous mixture contained in a cylindrical mould with the simultaneous action of a vertical static compaction and of the shearing action resulting from the rotation of the mould on its inclined axis. The compaction data is measured and recorded during the test.

Robust thus light high stiffness steel monocoque structure, incorporating pneumatic cylinder for vertical load application and electromechanical mechanism for the gyration system with exclusive mould rotation system, granting high accuracy and repeatability of test results, together with stiffness and angle stability values widely within the limits defined. Touch-screen user-friendly integrated control panel, large display showing the test graph in real time, on board firmware including 12 languages. Possibility to remote test control by PC.
