Gyratory Compactors

These Gyratory Compactors have multiples uses for both asphalt and concrete applications. They 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. They 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.

These gyratory machines have been designed 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. Both Gyratory Compactors are 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-5951.4F 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. The HA-5952.4F is designed for research purposes, which allows the electro-mechanical compactor to adjustment the gyratory angle This angle can be set in a range between 0° and 3°, during compaction, real-time direct shear and torque measurement.

Features:

• Rigid steel frame ensuring excellent angle control.
• Full color 7" touch screen control unit, running like a standard PC.
• Software for PC control data acquisition and processing.
• Electronic angle positioning.
• Dual angle option with double calibration AASHTO, EN and AS at 2 and 3.
• Automatic adjustment of the gyratory angle is defined by the user (GYRORESEARCH).
• Shear stress measurement (GYRORESEARCH).
• Optional integrated electromechanical extruder.
• Optional integrated balance.
