standard PC based on Windows operating system.
Software for PC control acquisition and data
Optional shear stress measurement.
Concept based on American DOT principles.
Cold mix emulsions which can be compacted.
Optional integrated balance.
Optional integrated extruder.
Gyratory angle adjustable from 0 to 2.4° (up to 3°).
Electromechanical version available on request.
GYROTRONIC – SUPERPAVE GYRATORY COMPACTOR
Gyrotronic compacts 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
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.
Using the proper perforated mould, the Compactor is able to run tests also on cold emulsified asphalt mix.
The acquired results are also employed in the investigation of volumetric and mechanical characteristics of the asphalt mix.
The machine is calibrated at Matest factory to the selected internal angle.
ON-BOARD TOUCH SCREEN or PC CONTROL
The touch-screen icon interface allows an easy set up of the parameters and an immediate automatic execution of the test, data acquisition and
processing, graphics and file. A remote test control is available through 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.
Hardware technical details: see catalogue at p. 19.
