Cover Story: A very common hazard in Rwanda is the instability of steep road cut slopes in lateritic soil. The paper presents the results of an experimental investigation into the microstructural, petrophysical, and geotechnical properties of lateritic soil from a road cut slope located in Kabaya (Rwanda), which was subjected to a landslide. The adopted multidisciplinary approach provided insights into the relationship between geotechnical properties and the microstructural, petrophysical, and chemical characteristics of the altered soft rocks. The study demonstrates the importance of such an approach since the failure mechanism is better explained if it is based on microstructural observations instead of considering the soil shear strength parameters only.
