ABSTRACT: This geophysical study conducted in the Penka-Michel region, in the West of Cameroon, analyzes the distribution of apparent resistivities and the lithological profiles of the soils, which are essential for road infrastructure planning. Vertical electrical soundings (VES) carried out at 51 points revealed a significant heterogeneity of resistivities at different depths (1.5 m to 27.5 m), corresponding to variations in the underlying materials. Areas with high resistivity, notably in the north and southwest, are dominated by more resistant materials, potentially exploitable for road construction. In contrast, areas with low resistivity, present in the east and south, indicate clayey or water-saturated soils, less suitable for road applications. These results provide the geophysical mapping needed to optimize the use of local resources and help improve the sustainability of infrastructure. Integrating geophysical data into soil management would help reduce costs, minimize the risk of premature degradation of infrastructures, and promote informed planning of road projects. This study fills an important gap in geophysical mapping in the region and calls for further research to refine the understanding of soils and their sustainable management in infrastructure projects.
