This paper describes a new triaxial apparatus for testing the thermo-mechanical behavior of soils. This triaxial apparatus accommodates samples 55 mm in diameter and 110mm in height. The cell is designed to perform compression tests under pressures up to 2 MPa and with temperatures ranging from 5°C to 90°C. The calibration of the device, as well as its precision and accuracy, is widely discussed in the paper. The related experimental procedures are also discussed. Finally, the results of tests performed on Kaolin are presented in order to highlight the features of the apparatus and to show some induced thermal effects on soils.
