One of the problems Nigeria has is unreliable road networks which has cause several untimely death and damages beyond recognition to human life. Non-destructive geophysical method involving very low frequency electromagnetic profiling was used to investigate the cause(s) of failure that occurred in the road that was constructed in less than two (2) years. Very low frequency electromagnetic profiling data were taken at 10 m interstation spacing along 2 traverses (the dual lane constructed there). KHFILT software was used for the processing of the data obtained. Conducting bodies which indicate clayey materials or linear geologic features such as faults, fractures, joints, and contact between two rocks were inferred from the interpretation. It was concluded that the road was probably constructed on clayey materials which was supposed to be excavated and refilled with laterites. From another angle, it was viewed that may be the engineers intentionally filled the sub-base with clayey materials during construction in order to get their financial returns which the masses are now paying for.
