The Resilient Modulus Testing System is expertly engineered for fully automated procedures to evaluate both the Permanent Deformation (when relevant) and the Resilient Modulus of soil or aggregate samples. This system meticulously applies a consistent axial cyclic stress across a fixed cycle duration to a cylindrical sample for a predetermined period. During the test, the sample undergoes a combination of dynamic cyclic stress and static-confining stress within a triaxial cell.
The VJ Tech Dynamic Servo Controller has adaptive PID Control, allowing the system to automatically adjust internal PID Settings to ensure the target load/displacement is met whilst the sample stiffness changes during the test, critical for Resilient Modulus tests that typically have a large number of cycles.
