A controller software with user interface was developed in Visual Basic that provides user friendly interfaces to control test phases and to enter input test parameters as well as programming capability to control sophisticated and to run high quality triaxial tests for measuring stress-strength-strain properties of soils in obtaining consistent and reliable results from the performed tests. When designing the controller software to administer the entire triaxial test process, the major variables considered primarily and desired to be controlled during the testing progress were: i) boundary drainage conditions (either drained or undrained); ii) imposed stress path; iii) magnitude of axial deformation; and iv) time rate. The software can consistently control the triaxial system applying either undrained or drained linear stress paths as well as performing isotropically (CI) and anisotropically consolidated (CA) or one-dimensionally (CKo) consolidated tests on soil specimens. Additionally, the software enables the user to access measurement instrumentation readings as well as to determine the specimen’s current stress-strain state through on-test transducers’ measurements.
