<p>The Trans African Highway Northern Corridor is the economical aortas to the landlocked country such as not only Kenya but also adjacent Uganda, Rwanda, Burundi. However, inadequate maintenance over the last 30 years has resulted in about 40% of this road network being “lost”, which in turn has produced higher vehicle operating costs and longer travel times for road users that are having a negative effect on the national economy. It is vital towards maintaining and improving pavement to understand well the cause of the destructive phenomena. It can be hypothesized that pavement damage occurs when the triangle balance is lost between the supportive strength of the subgrade base, the traffic load on the road surface, and pavement structure. The hypothesis is supported by present conditions analysis and non destructive inspection of the road fatigue destruction. This study analyzes and propose the current state of road maintenance and management issues of the Trans African Highway Northern Corridor in Kenyan region and explores effective human resource development approaches suitable for the region.</p>
