Description

沥青旋转压实仪

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 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.


B041 Gyrotronic - Superpave Gyratory Compactor-EN

Gyrotronic working principle precisely meets the internationalStandards specifications avoiding any interpretation deviation.Its stable mechanism with gears and bearers a is embeddedinside a sturdy frame.


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

Matest Gyratory Compactor is supplied complete with lubricant and power cord.

Optional extra are: moulds, filter paper, penetration pistons, extruder, bench, air compressor etc., to be ordered separately


Modes of operation:
• Compaction of specimen in accordance to the selected number ofrotations.
• Compaction of specimen upon reaching the selected height.
• Compaction of specimen upon reaching the selected density.
• The machine can also perform a final flattering cycle at“zero” angle to obtain specimens with perpendicular faces.
Data acquisition: number of rotations, specimen height, applied load(to ensure tolerances requested by the Standards)


Requires pressurized air, minimum 7 bar.

The Matest Gyratory Compactor is supplied complete with lubricant and power cord.
