B039A ASC-Asphalt Shear Box Compactor


The only electromechanical shear box compactor

The 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


  • 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
Dimensions: 788x1360x(H)1314mm
Weight: 1200 kg
