Assessment of Pavement Condition Index of The Federal Polytechnic Ado-Ekiti Campus Roads, Ekiti State, Nigeria

Abstract: Roads are built as infrastructure to facilitate mobility and accessibility of socio-economic activities in society. Highway is very essential in that it support the growth rate of the economy, agriculture, education and other sectors. Considering the benefits of road in economy growth, matters related to the development and maintenance of roads are a priority to be researched and developed in planning, implementing and maintaining them. One of the research targets is the paved roads within the Federal Polytechnic Ado Ekiti campus, which suffered significant defects, both minor and moderate damage. Although recently, most of these roads were rehabilitated but presently these roads are characterized by one defect or the other evidently noticed by some types of cracks on the surface of the pavements. The purpose of this study is to determine the type, extent and severity of these damages to the road surface, and then suggest measures for maintenance of these roads in order to optimize the durability of the roads. The application of the PCI is carried out by visual survey at the research location, determining the type and level of damage and measuring the damage dimensions which include length, width and depth, calculating the area of damage, analyzing the damage condition. The results of the analysis of the campus roads are classified with an average PCI value of 65. The appropriate improvement strategy suggested is routine maintenance.
