Quantify the Information Necessary to Guide Bridge Preservation Decisions

Bridge preservation is a systematic proactive effort to significantly extend the service life of a bridge or bridge elements, usually at the least possible cost. Many transportation departments may have a significant amount of largely empirical data on experiences with bridge preservation and have developed conclusions on the effectiveness of bridge preservation based on those experiences. However, few systematic studies have been done to measure, evaluate, and document the short- and long-term results and effects of bridge preservation actions. No attempts have been made to gather and collate high-quality data, properly analyze the data, and draw conclusions about the costs, effectiveness, and longevity of the preservation action. It is difficult to examine such issues as how long the service life of the bridge/bridge element is extended or what the effects of the various, commonly used preservation actions are on the life cycle costs of bridges. Most conclusions reached by bridge practitioners are on the basis of intuition or simple common sense backed up by some experience. It is difficult to translate these conclusions into coherent and convincing arguments that will persuade legislatures and agency upper management to support and adequately fund aggressive and well planned programs of bridge preservation. The collection of the data necessary to support analysis of the effectiveness and economics of bridge preservation activities should be addressed in a logical sequence, starting with short-term studies of existing data and moving to future data collection that is targeted at specific elements of the performance of bridge preservation actions. The material collected will be organized into a handbook for bridge owners to use as a guide to the most efficient and effective decisions for the maintenance and preservation of bridges. Recommendations will be made on how this guidance should be included in existing or new AASTHO specifications or guidance. The objective of the proposed research is to improve the decision process for setting bridge preservation activities and preparation of guidelines. The research will produce recommendations and a handbook for possible adoption by AASHTO.
