The behavior of soils under high temperature is very important. Previous studies have revealed that engineering properties of soils change depending on temperature. For instance, increase in temperature generally increases volumetric deformation and hydraulic conductivity of soils. In this study, in order to stabilize these changes and optimize engineering properties of buffer soils, fiberglass additives were added to the sand-bentonite mixtures and shear strength behavior under room and high temperatures was investigated. Fiberglass is widely used in the construction industry and many other industries for thermal insulation purposes. The test results showed that the shear strength of fiberglass added sand-bentonite mixtures changed negligibly under high temperature compared with under room temperature.
