Subject(s): Online resources: Bibl.nr: VTI P0409:523Location: Abstract: As highway agency budgets shrink, highway agencies are moving toward a policy of pavement preventive maintenance and away from worst-first programming. Preventive maintenance is a systematic process of applying a series of preventive maintenance treatments over the life of the pavement to extend pavement life, and minimize life-cycle costs. Although pavement preventive maintenance is believed to result in lower agency costs, improved pavement conditions, and increased customer satisfaction, these programs continue to face many obstacles. Among these obstacles are lack of proof that preventive maintenance is cost effective and insufficent guidance on when preventive maintenance treatments should be applied. The primary objective of this research was to develop a methodology for determining the optimal timing for the application of preventive maintenance treatments to flexible and rigid pavements. A secondary objective was to create a user-friendly tool to aid in the implementation of this methodology.
