Resilient Modulus Testing System

This series of high-quality, electromechanical or servohydraulic, closed-loop controlled triaxial load frames fulfil the criteria to perform resilient modulus tests.
These machines are characterized by their high levels of accuracy for static and cyclic automatic loading possibilities. GEOsys software enables us to produce all types of wave shapes, such as sine, square, haversine or different customized wave shapes. Thanks to the integrated keyboard, or alternatively the external controller, the operation of the test device is very user-friendly, meaning highly customized tests can be run. This configuration is ideal for educational and research purposes.
