GEOTECHNICAL INVESTIGATION OF FAILURE OF THE ROAD SECTION ALONG MAAI MAHIU-NAROK ROAD, 5.4 KM FROM MAAI-MAHIU

Abstract
Roads are integral part of land transport system. A country’s road network should be efficient
enough in order to maximize economic and the social benefits. They contribute significantly in
achieving the national development and enhancing the overall performance in social functioning
of the community. It is acknowledged that roads enhance mobility of people and goods and
therefore alleviates poverty levels. It is true that transport must start off first for any economy to
grow, which will in return stimulate other sectors towards development in an orderly fashion as
once said by John F Kennedy, “It is not strong economies that give good roads; but rather, it
is good roads that give rise to strong economies!”
The main aim of the study was to establish the possible causes of the failure of a road section
along the Maai Mahiu-Narok road, 5.4 km from Maai Mahiu town and recommend remedial
measures to rectify the problem and thus maintain uninterrupted flow of traffic.
Field, laboratory and desk research was done and the findings indicated that the failure was as a
result of the subterranean erosion along the existing fault line which occurred due to heavy
flooding.
In-depth geological and geotechnical research for the area proposed for road construction was
recommended. Proper designs of roads which can survive in that condition and proper
channelization of surface run-off were also among the recommendations.
