ABSTRACT

This project was executed in order to investigate into the level of service of Egbejila Road Ilorin west Local Government Kwara State and improvement options. It was carried out to determine the rigidity quality, traffic characteristics and traffic volume study of the road, which was put into consideration in order to know what really cause the failure and how to determine the improvement option for such road. It was also discussed; some of the possible effect of contraction which leads to structural failure of defect of potholes, washout, suited culvert, edge brake etc. The use of questionnaire was introduced to know the opinion of people in Egbejila Community on what are the problems faced regarding the specific road. It was also discussed; the common types of pavement failure in Egbejila road.
