Proposed AASHTO Guide for Bridge Preservation Actions

Many transportation departments have significant practical experience with bridge preservation and have developed conclusions regarding the effectiveness of bridge preservation actions based on those experiences. However, limited efforts have been made to identify, measure, evaluate, and document the short- and long-term performance of specific bridge preservation actions. Bridge preservation consists of actions to deter or correct deterioration of a bridge to extend its useful (service) life and does not entail structural or operational improvements beyond the originally designed strength or capacity of the bridge. Often practitioners apply preservation strategies on the basis of judgment or common sense using available resources. However, it is difficult to translate these strategies into coherent and convincing arguments in the absence of a quantitative measurement of bridge preservation effectiveness. The objective of this research is to develop a bridge preservation guide for possible adoption by AASHTO. The proposed AASHTO guide shall be developed based on data to be collected from representative agencies. At the minimum, the guide shall include: (1) a catalog of bridge element preservation actions and (2) the criteria and selection methodology of bridge preservation actions with associated costs and benefits for use in life cycle cost analysis and possible integration into a bridge management system.
