ABSTRACT
The primary objective of this work is to form the foundation of a Road Management Maintenance System (RMMS) that Road Maintenance Agencies like FERMA can immediately implement to make better decisions pertaining to rehabilitation options. Further, this is to allow for appropriate decisions about the best type of maintenance and rehabilitation interventions to apply to the poor state of arterial roads taking into consideration various factors, least of which are the type and extent of distress present and the benefit cost analysis. The outcome of this work will assist sub-Saharan Africa, but principally Nigeria, in their goal of fostering economic growth and creating a more sustainable transportation network. Recommendations on how to simplify input factors necessary for Nigeria to initiate a database and prepare more regionally specific designs have been made, including traffic, climatic and subgrade classifications. Economic analysis included present worth of costs (PWC) that were derived from condition rating curves specific to intervention pavement life and performance. Based on preliminary findings, subject to field validation, a chip-seal specific rehabilitation strategy for low volume federal roads is more cost effective over the 20-year analysis period and 1-lift Asphalt Concrete (AC) is more cost effective over the 20-year analysis period for high volume federal roads. Recommendations for further research have been made.
