SERVICE LIFE ANALYSIS FOR MANAGING ROAD PAVEMENTS IN MEXICO

This paper presents the implementation of a comprehensive analytical and economic evaluation methodology and software for pavement management applications in Mexico. The software incorporates the state-of-the-art condition deterioration prediction models for asphalt, concrete and other pavement types. The program generates the network-level annual and multi-year work programs and budgets for roads and highways taking into account the agency costs, vehicle operating costs, and other user costs associated with the pavement condition during the service life. Maintenance treatments are selected considering distress, roughness and serviceability, and deflection data. Priority ranking is based on maintenance urgency and benefit-cost ratio. Examples of service life analyses, based on the work program reports generated for the cities of Leon and Saltillo, show the use of savings in user costs as a rational method of benefit calculations.
