Soil collapse potential is a crucial factor in geotechnical engineering, and heating collapsed soil under different temperature and water content conditions can significantly affect its geotechnical properties, including collapse potential, maximum dry density, optimum water content, liquid limit, and plasticity limits. A research study was performed on soil samples with different water content (0%, 10%, 15%, and 20%) tested at temperatures of 50°C, 100°C, 150°C, and 200°C. The relationship between soil temperature distribution and the distance from the heating source was examined. The findings showed that heating the soil can improve its geotechnical properties. The collapse potential of the soil decreased as the temperature increased, indicating a decrease in moisture content due to evaporation. Furthermore, as the temperature increased, the soil's maximum dry density and optimum water content also increased, indicating an improvement in the soil's compaction properties. The liquid limit of the soil increased up to a temperature of 100-150°C and then decreased, while the plasticity limits decreased with increasing temperature. These findings have significant implications for geotechnical engineering applications, such as building foundations, embankments, and pavements.
