Asphalt Shear Box Compactor

The only electromechanical shear box compactor

The Asphalt Shear Box Compactor ASC is being used in FHWA Contract “Deployment of Performance Based Technologies for Mechanistic-Empirical Pavement Design and Resource Responsible Materials Design” to fabricate specimens for Level 1 analyses using the AASHTOWare Pavement ME Design software.
It is the only compactor capable of fabricating specimens for all of the following mechanistic-empirical performance tests:

1. Dynamic Modulus, AASHTO PP 61
2. Repeated Load Permanent Deformation, AASHTO TP 79
3. Flexural Fatigue, AASHTO T321
4. Low Temperature Creep and Strength, AASHTO T322

MAIN FEATURES:

• Extremely sturdy fabricated frame combined with precision machined components
• Servo hydraulic vertical ram with integral hydraulic power supply
• Precision electro-mechanical shearing motion
• Integral specimen extruder
• Electronic control unit with touch screen color display (no need for PC)
• Unlimited memory storage with: 2 USB ports, 1 SD card slot , RS232/485 serial port
• The compaction cycle can be programmed by specifying vertical stress/load and test termination conditions; Number of cycles, Specimen height and/or density
• ASC can be equipped with a precision load cell for vertical and shear stress measurement, upon request
• Optional built-in mould heater

Power supply: 230V 1ph 50/60Hz
