Resilient Modulus Triaxial Cell

The Resilient Modulus Triaxial Cell has been designed to facilitate Resilient Modulus testing of aggregate and soil materials.

The innovative design allows the acrylic chamber to be removed over the top of the cell allowing the operator ease loading piston and attachment of deformation equipment directly to the test specimen. Other features include:

  • Comes ready to test 6x12-in test specimen
  • Loading Piston 1-½-in stainless steel piston
  • Mounting bracket for two displacement transducers
  • Platens of 316 stainless steel
  • Acrylic chamber with SS bands for 40 psi pressure
  • Optional provisions for 150 psi confining pressure
  • Base equipped for dual ports to each platen


A double slide plate that both fixes the piston to the upper platen, while facilitating alignment. The piston transfers the axial force through a spherical seat. Provisions have been made to mount dual displacement transducers to the axial piston. A latching system allows quick assembly of the head plate and tie rods to the base plate.

Applicable Standards:
AASHTO T-307
