This paper presents the results of an experimental investigation carried out to study the engineering properties of soft Bangkok clay subjected to temperatures changes varying from 25°C to 90°C. Details of a modified triaxial test apparatus that can handle temperatures up to 100°C are also presented. The experimental program includes series of drained and undrained compression triaxial tests, and flexible wall hydraulic conductivity tests conducted at different temperature levels. In the range of temperatures investigated, soft Bangkok clay was found to exhibit temperature induced volume changes that depended mainly on the stress history and stiffness. Hydraulic conductivity was found to increase as temperature increased. The results of this study provide additional data that can enhance the understanding of the thermo-hydro-mechanical behaviour concepts of saturated clays.
