ABSTRACT
Road transportation is one of the most promising and potent means for rapid industrialization and agricultural advancement. It plays an important role in economy of the country. This study accesses the pavement failure along Eyenkorin-Ogbomoso road using GIS approach. Coordinates of all failed portion along the alignment were located and describe while land use elevation map and road failure map were produced across the stretch were obtained with the use of Global Positioning System (Garmin 76GPS receiver) in UTM coordinate system. The dimensions of individual pavement failure was measured and recorded against their respective location coordinates, the imagery of the road was captured using Google Earth software. The imagery was geo-referenced and the failure coordinates plotted over the rectified imagery and the geo-database was evolved in ARCGIS 9.2 and the failure dimensions entered into the database. The length of the road is 47.6Km of single carriageway stretch between Eyenkorin – Ogbomoso transversing about fifteen communities. The pavement structure is made of 7.3m wide asphaltic concrete carriageway and 2.75m surface dressed shoulder on either side. The road has undergone series of palliative work since its existence. Presently, the road is in a very deplorable condition characterized by different failures such as cracks, peeling Edge, eroded shoulder, Potholes, Potholes, Rut, Raveling, and Washout etc. The outcome of this study reveals that adopting GIS to monitor road pavement failure is very advantageous for highways upgrading.
