The exposed cohesive soils to temperature can face considerable physical and mechanical characteristics changes. Therefore, understanding the environmental events influences on the soil geotechnical properties is essential, which is significant in the rainy and cold places such as in Sulaimani city, northern Iraq. This experimental study examines the temperature changes (10o C, and 50o C) impacts on the durability of stabilized cohesive soil using 0%, 5%, 10% and 15% hydrated-lime added as a replacement on the soils dry mass. Consistency, unconfined compression, and compressibility characteristics were evaluated. Under the applied circumstances, a decrease was noticed in the magnitudes of liquid limit and plasticity index, while plastic limit generally increased within hydrated-lime percent increase. The study yielded an appreciable improvement of the cohesive soil’s strength and compressibility properties with time progress, especially after the stabilization process is achieved.
