Abstract: Most developing countries face the challenge of inability to successfully adopt sophisticated commercial Pavement Information and Management System (PIMS) that incorporates pavement condition rating system. While, cities with populations of <22,500 can easily function using a manually-operated simplified PIMS, agencies with bigger population and bigger road network to manage, have to use computerized PIMS to effectively deal with the voluminous amount of generated data. The major challenge of this research therefore, was to accurately computerize the manual PCI-based condition rating system and make it user-friendly and effective for pavement management. A source code was developed within MATLAB software and used for computations while, Visual Basic programme was incorporated for the graphical display of results and generated reports. In order to validate, the constructed condition rating system, 12 road sections were selected and surveyed. Condition rating was performed for these road sections using both manual method and the constructed computerized system. The comparison of the results shows that the constructed system is quite reliable as a PCI-based condition rating system.
