Gyratory Compactor, Research Model

The HA-5952.4F Gyratory Compactor has multiples uses for both asphalt and concrete applications. It can be used to simulate and reproduce real compaction conditions and road paving to determine the compaction properties of asphalts in compliance with ASTM, EN and AS standards. It can also be used to simulate the kneading action of concrete mixes and recreate compaction process in precast production lines according to NT build 427.

The HA-5952.4F has been built based on the U.S. DOT concept where compaction is achieved by the simultaneous action of a low static compression and a shearing action resulting from the motion of the axis of the mold, which generates a conical surface of revolution. It is primarily designed for research purposes, which allows the electro-mechanical compactor to adjust the gyratory angle. This angle can be set in a range between 0° and 3°, during compaction, real-time direct shear and torque measurement

It is designed according to the International standards, providing perfect and precise compaction through a stable mechanism integrated with a solid and heavy-duty frame. The HA-5952.4F Gyratory uses electro-mechanical compaction where the load is applied by an electro-mechanical cylinder with a load cell positioned directly on the vertical actuator for precise load measurement.
