“…The liquid limit and plasticity index of IBN and MKP soils (kaolinitic clay mineral) showed a decreasing trend with increase in temperature. In contrast to Gadzama et al [25] who used black clay (montmorillonite), they reported consistent trend for liquid limit decreasing with increase in temperature on one hand and on the other hand concluded that no actual relationship exists between temperature and plasticity index. However, both studies used tropical soils but of different clay mineralogy and composition.…”

“…Several geotechnical researches have used simple and multiple regression analysis to correlate and develop workable models [25,[53][54][55][56][57]. Gadzama et al [25] after establishing the effect of temperature on expansive soils used it along with other associated parameters to correlate and proposed useful model for CBR. The use of temperature as part of independent parameters to correlate the stiffness property (CBR) of soils has not been given much attention.…”

“…The use of temperature as part of independent parameters to correlate the stiffness property (CBR) of soils has not been given much attention. Thus, the statistical analysis in this study is a follow-up to Gadzama et al [25] who used highly expansive black clay soils which are completely different in terms of origin, formation and mineralogy composition from soils considered in this research. Simple linear regression model was formulated from laboratory results of IBN and MKP soils using Minitab R15.…”

“…Goodman et al [22] used field emission scanning electron microscopy (FESEM) data to show minimal changes due to temperature effect on the fabric of unsaturated clay. Previous research work in the literature shows that researchers experimented the effect of temperature on soil properties at the peak of 120 °C [24], 150 °C [25] and 400 °C [26]. However, researches on microscale analysis of soil due to temperature variations are not in abundance and the effects of varying elevated temperature on the scanning electron microscopy of soil are not well understood.…”

“…This study aims to experimentally evaluate the effect of elevated temperature on the geotechnical properties of clay soils (kaolinite). The study is a follow-up phase of previously published work of Gadzama et al [25]. The macroscale investigations which involve the laboratory testing are further enhanced qualitatively using microscale experiment (scanning electron microscopy) to explore microstructural behaviour of soils.…”

The engineering performance of soil after exposure to temperature is increasingly important in geotechnical and geoenvironmental engineering. Most thermal remediation of soil concentrates more on the remediation outcome and eliminates the effects temperature will have on the engineering properties of the soil itself. This paper presents the results of laboratory study conducted on two lateritic soils to investigate effect of elevated temperature difference on their geotechnical properties. The soils were classified as A-7-6 (8) and A-7-5 (4) based on the AASHTO soil classification system. After subjecting the soil samples to elevated temperatures (25, 50, 100, 150 and 200 °C), tests such as Atterberg limit, compaction, California bearing ratio (CBR), unconfined compressive strength (UCS) and scanning electron microscopy were carried on the samples. The results showed a decrease in Atterberg limit and increase in maximum dry density. The peak CBR for both the soils was obtained at 150 °C. The UCS increased with curing time but decreased with increased preheat temperature for both soils. The microanalysis result portrayed changes in morphological structure of fabrics which indicates a breakdown in the microstructural properties of the soil due to temperature variation. Generally, the statistical analysis of variance showed that temperature has significant effect on the geotechnical properties of residual soils.
