Preventive maintenance has the potential to improve network condition by retarding future pavement deterioration. The Virginia Department of Transportation uses its pavement management system to determine maintenance targets for each district. The districts then use these recommendations to select pavements that will receive maintenance and the types of treatments that will be applied. Each district has a different approach to preventive maintenance. There was a need for more consistent preventive maintenance practices across the state. This paper outlines the development of a district level preventive maintenance treatment selection methodology. The methodology proposed includes preparing a prioritized list of pavement sections, and selecting the projects that maximize the cost-effectiveness of the selected treatments subject to budgetary constraints set by the central office. To illustrate the application of the methodology, it was implemented in a prototype treatment selection tool and was run for each pavement classification in each district. The results were encouraging and suggested that the selection tool has the potential to be a very powerful decision support tool if the unit costs are representative of what the expected treatment costs are for each district.
