The large-scale triaxial testing systems are customized construction systems configured based on the testing requirements of the customer. These systems are used to perform static tests on specimens with large particle sizes, such as dam ballast, railway ballast, and gravels. The Large Diameter Dynamic Triaxial Testing System can apply up to 1000 kN load with a frequency of up to 50 Hz  on samples with a diameter of up to 600 mm. (An ultra-large triaxial system is available on request for sample sizes up to 1000 mm.) The wide column spacing enables the accommodation of large cells, even with environmental chambers and furnaces. The load frame features a pneumatic sliding system, which allows easy movement of the triaxial cell out of the loading area, making test setup handling easier for the operator. The powerful multifunctional GEOsys software supports all test procedures, providing easy access to all testing sessions.

The new fully automatic Resilient Modulus Testing System (RMTS) is based on our cyclic tabletop electromechanical Triaxial test System with closed-loop control of the axial load, displacement and confining pressure. The Cyclic load simulates conditions produced by traffic. The device with different components can comply with the requirements of AASHTO T 307-99, AG:PT/T053 and AS1289.6.8.1. As the device is based on our cyclic Triaxial test therefore can also be used to perform other dynamic and static tests such as Stress Path, cyclic strength, liquefaction, Ko- Consolidation, as well as conventional UU, CU, and CD tests with the addition of components for back pressure control and pore pressure measurement. GEOsys software in combination with this unit performs all your tests automatically and without operator assistance during the test period.

This series of Dynamic Triaxial test systems gives the possibility to perform large loads and frequencies on the required specimen size in combination of static or cyclic cell pressure. The Wide column spacing enables to accommodate large cells even with environmental chambers and furnaces. The Triaxial system can generate and apply different types of loading waveforms that can be given to the sample e.g. Sinusoidal, Square, Triangular, Rectangle, Ramp signal, and user-defined waveform. The dynamic servo hydraulic load frame has different models which could be selected per as required technical test specification of the user e.g: 1) Table top model 2) Floor type model 3) Twin type model (independent dynamic - static actuators)

The new developed cyclic tabletop electromechanical closed-loop controlled triaxial load frames are characterized by their high accuracy for stress-strain triaxial tests with static and cyclic automatic loading possibilities up to 10kN and 10Hz. The cyclic actuator is placed on upper traverse and has dedicated dynamic controller to run all cyclic loads required for different applications. The upper traverse can be adjusted per as the size of triaxial cell or other test applications. The test apparatus is suitable for compression and extension tests with isotropic or anisotropic consolidation and covering whole testing applications and comply with international standards.
