Spectroscopy to characterize expansive soils
2007 IEEE International Geoscience and Remote Sensing Symposium, 2007 Expansive soils are major geotechnical hazards that pose several problems on engineering structures causing billions of dollars of damage in many parts of the world especially at places where there are significant climatic differences between dry and wet periods (Gourley et al., 1993; Nelson and Miller, 1992).

Slope Crack Propagation Law and Numerical Simulation of Expansive Soil under Wetting–Drying Cycles
Sustainability, 2023 This study investigated the crack propagation law of expansive soil slopes under drying–wetting conditions and the influence of cracks on slopes by conducting a large-scale indoor slope test subjected to drying–wetting cycles. The change in soil moisture

Hydromechanical behavior of unsaturated expansive clay under repetitive loading
Journal of Rock Mechanics and Geotechnical Engineering, 2021 Compacted layers of expansive soils are used in different engineering projects, such as subgrades, engineered clay barriers, and buffers for radioactive waste disposal. These layers are exposed to a variety of stresses and wetting conditions during field

Experimental Study on Expansive Soil Improved by Lignin and Its Derivatives
Sustainability, 2023 Expansive soil covers the vast area of Mengzi, Yunnan, China, and creates numerous hazards for construction projects. When treating expansive soil, a modifier is usually added to inhibit its expansion and increase its strength. Lignin and its derivatives
