ABSTRACT
This research assesses the various factors responsible for road failures in the
southwestern and south-southern parts of Nigeria with the aim of reporting
findings to the public domain. The research further stressed the importance and
relevance of geophysics in evaluating civil engineering structures such as
roads. The above goals were met by studying the results of surveys carried out
by researchers in southern Nigeria. Electrical Resistivity and Electromagnetic
methods have been used to evaluate subsurface integrity around the southern
part of Nigeria. The VLF-EM methods were used by researchers to carryout survey
in these areas which showed the presence of near surface linear geologic
structures of varying lengths, depths and attitude, which suggest probable
conductive zones that affect the foundation of roads. The quantitative
interpretation of VES results obtained from various parts of the southern part
of Nigeria established the presence of clay materials which is indicated by low
resistivity values or high conductivity values.
