ASPHALT SHEAR BOX COMPACTOR (ASC) - THE ONLY ELECTROMECHANICAL SHEAR BOX COMPACTOR

Code : B039A

STANDARD: ASTM D7981-15 Standard practice for compaction of prismatic asphalt specimens by means of the 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:

Dynamic Modulus, AASHTO PP 61

Repeated Load Permanent Deformation, AASHTO TP 79

Flexural Fatigue, AASHTO T321

Low Temperature Creep and Strength, AASHTO T322

ASPHALT SHEAR BOX COMPACTOR (ASC)

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 (user programmable).
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.
Precision load cell(s) for vertical and shear stress measurement.

Optional built-in mould heater.
