This study investigates the causes of recurring road failures at Ekiti State University, Ado-Ekiti, Nigeria, using geophysical methods. The research aims to identify subsurface conditions contributing to these failures, assess the geological and geotechnical properties of the soil and rock, and recommend sustainable construction practices. Electrical resistivity using dipole-dipole configuration and two-dimensional (2D) electrical imaging where used. Data were collected through Ohmega Resistivity Meter, electrodes, and connecting cables, with measurements processed using Dipro-Win software. The results revealed four geological formations: topsoil with resistivity values ranging from 22 – 128 Ωm, a weathered layer (128 – 737 Ωm), a partly weathered basement (737 – 4232 Ωm), and fresh basement rock (>4232 Ωm). Weak zones with low resistivity, suspected as clayey material, were found between stations 3 and 7, with a thickness of less than 2.5 meters. These zones are associated with road cracks and failures. Moderate resistivity zones (likely laterite) between 7 and 10 meters demonstrated field competence. Below these layers, partly weathered and fractured zones were identified above fresh basement rock, with signs of weathering toward the east of the study area. According to the findings, the electrical resistivity approach was a useful tool for identifying the reasons behind road failures along Ekiti State University's Management Science Road to college of medicine. For road rehabilitation projects, the discovered subsurface anomalies such as inadequately compacted soil and underground water channels offer important insights. The study shows how geophysical techniques canZbe used to solve problems with road infrastructure and shows how they can be used more widely in road engineering and maintenance projects.
