This research explores the responses of reconstituted Kaolin clay samples due to simulations of wildfires in the laboratory using heat guns for control heating. Two laboratory geophysical methods, bender element and electrical resistivity, were used to detect the changes in soil’s mechanical (shear modulus, Gmax) and hydraulic properties (electrical resistivity, ρ) in real time, while soil specimens were heated, up to 60°C, to partially represent the temperatures in a wildfire. Measurements were compared with samples that had not been heated. Results show that the Gmax values for the controlled samples were about 25% greater than those that were heated, which implied that heating causes soil strength reduction. Additionally, the electrical resistivity for the controlled samples was 55% higher than that of the heated samples, meaning that heating caused the kaolin specimens to be less permeable. Correlations between Gmax versus temperature (T) and water content were developed. Results also allowed for the development of electrical resistivity, temperature, and water content correlations.
