This thesis on a project undertaken by the author is aimed at providing explanation of the basic theory of the work of road design and its associated activities also, to cover practical methods of working. In pursuit of the meaningful completion this project a lot of investigation was embarked with principles and practice of road construction. The total distance of route was determined and stations established bearing in mind the intervisibility of the stations. Leveling was carried out to obtain information on the profile of the route for proper earthwork knowledge which theodolite traversing was carried out to obtain the plan and horizontal alignment of the route Soil analysis, gave the proper constitute of the soil which was also carried out to and in the pavement design. Therefore the pavement design of the route was abased on the results obtained from the soil analysis using the CBR method.
