TRIAXLAB Automated Triaxial Testing System is specifically designed for advanced soil testing. is an outstanding system specifically designed for advanced soil testing. This system can be used from educational to construction engineering laboratories to reduce to the absolute minimum any form of manual intervention.
Based on the unparalleled performance of CDAS and flexibility of TestLab Software, the new TriaxLab Automated System is the optimized system to perform automatically total and effective triaxial tests such as:
- CD Consolidated Drained test
- CU Consolidated Undrained test
- UU Unconsolidated Undrained test
- Standard stress path
- Optional K0 tests
- Optional Permeability tests
Main Features
- Automatic execution of 5 independent triaxial tests from start to finish.
- Type of tests: total and effective stress, standard stress path, optional K0 and optional permeability.
- Servo feedback controlled precision pressure (Pressurematic) generation system.
- Real time graphing and configurable real time transducers.
- Pre-programmed user-friendly “Method files” through the TestLab Software.
- Compact and versatile for improving productivity and cost effectiveness.
- No need of air source.
The TRIAXLAB automated system basically consists of 3 major groups:
Load frame and triaxial cell with accessories
Control system based on the CDAS Control and Data Acquisition System and TestLab Software controlled by PC
Data Acquisition System comprising:
- 1 load cell for axial force
- 1 displacement transducer for axial displacement
- 2 pressure transducers for cell pressure and back pressure
- 1 pressure transducer for pore pressure
- 2 Pressurematic for pressure / volume change
To suit the specific customer’s requirements the 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.

S303 CDAS and TestLab Software
Pavetest’s compact Control and Data Acquisition System (CDAS) delivers unparalleled performance, real time control and ultimate versatility in acquisition and provide a flexible and user friendly testing solution for soils when coupled with the TriaxLab Automated System and the Cyclic TriaxLab Automated one. The CDAS provides excellent waveform fidelity from integrated acquisition and control functions, with low level sampling at speeds of up to 192,000 samples per second simultaneously on all channels (using up to 64x oversampling). S303 CDAS provides an optimized solution for the TriaxLab Automated Systems. The CDAS works with close synchronization to the TestLab software providing dynamic and precise servo control of the TriaxLab frame, Pressurematic systems. Acquisition and control is provided for:
- Vertical load and displacement
- Confining and back pressure (through the solenoid valve)
- Volume change and water pressures
- Local strain
