Abstract

Geoelectric investigation, involving electrical resistivity method, was carried out within a site earmarked for an airport runway in the Mambilla Plateau, Taraba State, Nigeria. The objective was to generate surface and subsurface geologic information required for the location and design of a stable airport runway. The data acquisition involved the Vertical Electrical Sounding (VES) which utilized Schlumberger array and 2-D subsurface imaging technique which utilized the dipole-dipole array. 28 VES stations were occupied and 5 dipole-dipole profiles were traversed. The VES interpretation results were used to construct 3 Geoelectric sections and the isopach map of the lateritic (competent) layer. The dipole-dipole data were inverted to 2-D subsurface images using DIPRO Software. 4 lithologic layers were delineated. These included the topsoil, the lateritic hardpan, weathered basement and the fresh basement bedrock. The study concluded that the subsoils on or within which the proposed runway pavement would be founded were generally competent having both resistivity and thickness values that were higher than the established threshold of 1.5 - 2 m thickness of laterite and layer resistivity of 600 ohm-m.
