HA-5950.4F Superpave Gyratory Compactor

This Gyratory Compactor is used to simulate and reproduce the real compaction conditions of actual road paving operations in determining the compaction properties of asphalt. Its fully-automatic compaction operation provides that both rotary and vertical forces are applied to the specimen by the mechanical head. The gyratory’s rigid, steel frame ensures that excellent angle control is maintained through the testing operation.


Load is applied by an electro-pneumatic cylinder, which is servo-controlled by a precision pressure regulator while the height is measured by a linear transducer. Gyratory motion is generated by an eccentric high-precision system allowing an easy set up with precision and constant angle of gyration. The rotation speed is controlled by an inverter through on-board computer control.

In addition to testing standard mixes the Gyratory can also test cold emulsified asphalt mixes using one of the available perforated molds. Machines are factory calibrated to the selected internal angle.The touch-screen, icon-based interface allows for easy test parameter set up and test execution, as well as data acquisition and data processing.

  • Rigid steel frame ensuring excellent angle control.
  • Electro-pneumatic action with servo-controlled regulator.
  • Full-color, touch-screen control unit
  • PC Software for control, acquisition and data processing.
  • Optional integrated balance.
  • Optional integrated extruder.

The machine provides direct connection to a LAN network and the internet, which allows for remote machine control, as well as remote communication
with technicians for immediate diagnostics and problem solving and for software updates.
Unlimited memory storage with: 2 USB ports, 1 SD card. Machine is factory calibrated and supplied with the internal angle set to 1.16° as rspecified by ASTM, AASHTO Specifications
