AN ECONOMIC CONSIDERATION OF PAVEMENT OVERLAY DESIGN STRATEGIES: A CASE STUDY OF BAUCHI - JOS ROAD

📄 Project Abstract

Pavement deterioration is revealed through many indications, among which is roughness of its surface which is a collective consequence of the various deterioration factors of the pavement. The economic impact of road deterioration is considerable, and usually outweighs the consideration of riding comfort, and thus providing the strongest objective for evaluating roads improvement policies and corresponding cost implications. This work attempts to address the effect of applying different strategies of overlay as remedies to arrest the escalation of costs incurred by both road agencies and users, and finally, determines the economic optimum strategy that minimize the total system cost. In order to effectively achieve this, six different strategies (the do nothing, 200mm,150mm 100mm,75mm, and 50mm) were investigated to reflect both service performance and economic evaluation. Relevant data for evaluating performance were collected from the pavement evaluation unit (PEU) of the Federal Min...
