Pavement 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 complete “turn-key” systems. Through advanced software and hardware, these systems are especially well-suited to test coarse, granular materials and essentially eliminate all vibrations that would disturb specimen during testing.
