AASHTO Guide to Bridge Preservation Actions Implementation Workshops

Bridge preservation is a cost-effective approach to manage an inventory of bridges. 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. Research was performed under NCHRP Project 14-36 by the University of Colorado Boulder to develop bridge and deck preservation guides for possible adoption by AASHTO. The proposed AASHTO guides were developed based on data collected from representative agencies and include: (1) catalogs of bridge element preservation actions and (2) the criteria and selection methodologies of bridge preservation actions with associated costs and benefits for use in life cycle cost analysis and possible integration into a bridge management system. The AASHTO Committee on Bridges and Structures balloted and passed for adoption two guides: (1) AASHTO Guide to Bridge Preservation Actions (published July 2021) and (2) AASHTO Guide to Preservation of Highway Bridge Decks (pending publication). The purpose of this project is to develop and hold implementation workshops for state DOT, local public agency, and consultant bridge practitioners to implement bridge preservation practices, reduce bridge infrastructure life-cycle costs and keep bridges in good or fair condition longer.
