Direct Shear Test


The GCTS Direct Shear Testing Systems can perform both constant normal stress and constant normal stiffness direct shear tests on either asphalt or soil specimens. These systems feature closed-loop servo control of the shear load and normal load actuators, and are completely "turn-key" systems. Through advanced software and hardware, these systems essentially eliminate all vibrations that would disturb specimen during testing. 

 

The GCTS Direct Shear Systems feature:

 

  • Complete "turn-key" automation
  • Closed-loop digital servo control of double acting (push/pull) shear load actuator with up to 1000 kN (100 ton) capacity and up to ±50 mm stroke
  • Axial actuator with up to 50 kN capacity and up to 50 mm stroke
  • Rectangular or cylindrical specimens up to 300 mm in side or diameter
  • Can perform both constant normal stiffness and constant normal stress tests
  • Systems available with varying load capacity and specimen dimensions based on the needs of the operator
  • Conforms to AASHTO Standard T 236

The GCTS Direct Shear Systems feature electro-hydraulic closed-loop digital servo control of the shear and normal load actuators. This allows for complete automation of the testing procedure, making performance of the test simple and accurate. The systems can easily perform both constant normal stiffness and constant normal stress tests.
