B041 EN Gyrotronic - Superpave Gyratory Compactor - EN

( Asphalt )

  • EN 12697-10
  • EN 12697-31

This Gyratory Compactor, entirely developed and manufactured by Matest, is used to simulate and reproduce the real compaction conditions under actual road paving operations, hence determining the compaction properties of the asphalt.

Such compaction is achieved in a fully automatic way, by combining the rotary action and the vertical resultant force applied by a mechanical head. The Compactor comprises a highly rigid steel frame ensuring excellent angle control.

Load is applied by an electro-pneumatic cylinder, servo-controlled by a precision pressure regulator; 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.

Using the proper perforated mould, the Compactor is able to run tests also on cold emulsified asphalt mixture.

The acquired results are also employed in the investigation of volumetric and mechanical characteristics of the asphalt mix.

The touch-screen icon interface allows an easy set up of the parameters and an immediate automatic execution of the test, data acquisition andprocessing, graphics and file. A remote test control is available trough a dedicated software, provided in bundle.
Direct connection to Intranet (through LAN network) and Internet to establish a remote communication and receive an immediate diagnostic of
potential problems from Matest technicians, or for software updates.
Unlimited memory storage with: 2 USB ports, 1 SD card.

The machine is calibrated at Matest factory with the internal angle set according to the Standard chosen by the customer:

  • Angle set to 0.82° to meet EN 12697-10, EN 12697-31
  • Data acquisition: number of rotations, specimen height, applied load (to assure tolerances requested by the Standards)
  • Requires pressurized air, minimum 7 bar.
