STANDARDS: ASTM D7181 | ASTM D2850 | ASTM D3999 | ASTM D4767 | ASTM D5311 | BS 1377:7 | BS 1377:8 | AASHTO T307-9

MAIN FEATURES
Automatic execution of static and dynamic triaxial
tests including effective stress and standard stress path.
4 axis control and 16 channel control Data
Acquisition System.
Servo feedback controlled precision pressure
(Pressurematic) generation system.
Digital Servo-Pneumatic Control to provide accurate
loading wave shapes up to 70 Hz.
Real time charting.
Compact and versatile for improving productivity and
cost effectiveness.
Pre-programmed user friendly “Method files”
through the TestLab Software.
Possibility to upload user-defined wave-shapes (e.g.
earthquakes time series) through Replay Editor.
Fully configurable to suit a large range of testing
applications including maximum shear modulus
calculation through bender elements option.
Programmable Dashboard display showing real-time
system status and test result.

The Cyclic TriaxLab automated with its innovative features represents
the most ideal solution for modern laboratories that need to
investigate the effects of vibration and dynamic loading for soil and
unbound granular materials.
Typical applications include:
Civil engineering including seismic and blasting analysis
Environmental engineering
Construction and architectural design
Advanced research on soils

Based on the 4 axis control and 16 channel control and Data
Acquisition CDAS, Matest Cyclic TriaxLab has provision for:
Vertical load tension/compression up to 9 kN
Vertical displacement up to 50 mm
Cell pressure up to 2000 KPa
Back pressure up to 2000 KPa

The Cyclic TriaxLab automated system is subdivided into 3 major
groups similarly to the TriaxLab Automated System:
Fully digital controlled load frame and fit for purpose Triaxial
cell with accessories
Control system based on the CDAS
Data Acquisition System comprising:
– 1 submersible load cell for axial force
– 3 pressure transducers for cell pressure, back pressure and
pore pressure
– 2 Pressurematic for pressure/volume change

To suit the specific customer’s requirements the MATEST Cyclic
TriaxLab Automated System basic configuration can be modified by
adding or removing the hardware elements which are controlled and
monitored under a closed-loop integrated system with the CDAS
and TestLab Software.
Pre-programmed “Method files” offer the operator the unique
opportunity to run a range of tests without the need for specific
computer programming. The possibility to customize the Method
files is also given to the operator granting ultimate flexibility and
versatility.
