It is important to ensure that water is prevented from getting in contact with the subgrade in order to maintain its stability and a stable road pavement. The activities of the local road maintenance as well as the groundwater fluctuation along Minna-Kataeregi road were investigated. This was in order to ascertain the impact of the local road maintenance on the performance of this road. The result shows that there is considerable seasonal moisture change along the studied road. The activities of the Local road maintenance expose the subgrade to water as well as raising the water table. This resulted in instability of the subgrade that has translated to poor performance of the road instead of improving the road.
