Electromechanical Shear Box Compactor


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 andResource Responsible Materials Design” to fabricate specimens for Level 1 analyses using the AASHTOWare Pavement ME Design software. 


It is 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

B039A 沥青混合料剪切压实仪 (ASC)

A Rugged Design For Specimen Preparation

Asphalt technologists are acutely aware of the importance of a representative specimen during any laboratory performance testing.

Shearing motion of the ASC replicates the conditions offield compaction in order to reproduce the field properties of asphalt,quickly and easily under the controlled conditions of a laboratory.

The ASC compacts large asphalt prisms that can be sawn to producefour to six beams or slabs for laboratory wheel tracking; or the prismcan be cored to produce three to four 100 mm diameter cylinders, allhaving essentially identical properties.


The electronic control unit, with touch screen color display, makes aPC an option.

The user friendly touch-screen icon interface allows for easy set upparameter entry, enables immediate (fully automatic test execution)data acquisition/processing, test report, and data file generation.

A LAN connection to Intranet/Internet enables remote communicationto receive immediate diagnostic analysis and technical support fromMatest technicians, and/or software updates.
