Abstract

Bridge preservation planning has gained significant interest in recent years due to its high potential to provide better asset management programs. The use of bridge preservation improves the life-cycle cost of the asset as preservation actions should increase the service life at a reduced cost compared to repair or rehabilitation. This project aims to develop a framework for bridge deck preservation tool that can help engineers at state and local departments of transportation choose the optimum preservation action for a given bridge deck. The proposed tool consist of five modules: user inputs, selection of maintenance actions, analytical algorithms, optimization, and output. A comprehensive literature search of available maintenance actions for concrete, steel and timber bridge decks was completed including service life and cost information for each of the maintenance actions. WJE also developed an innovative probabilistic algorithm to provide estimate for service life extension associated with the different maintenance actions based on the pre-existing condition of the bridge deck, traffic loading, and environmental exposure, among other factors, with the estimated uncertainty.
