• Abstract:
  Bridges are a key element of the transportation system because they control system capacity and are normally built at ; the highest cost to the system. Once a bridge reaches its useful design service life, it needs to be replaced or ; reconstructed in order to safely accommodate traffic and efficiently utilize the system. While highways can be repaired ; relatively quickly, bridges require special planning, engineering, materials procurement, and longer periods of ; construction time. This study synthesized current state-of-practices of rapid bridge construction methods, developed a ; decision-making framework for determining the feasibility of adopting rapid bridge replacement/construction, that ; considers issues of criticality of the bridge, contractor’s prefabrication ability, contractor’s construction management, ; and agency and user costs of bridge construction. The findings provide highway agencies with a framework to determine ; whether it is appropriate to utilize rapid bridge replacement/construction techniques for specific bridges. Based on these ; findings, a decision support framework using Analytical Hierarchy Process (AHP) is presented to allow for agencies to ; rank order priorities amongst those assets (bridges) that are determined to be candidates for rapid ; replacement/construction. Finally, a preliminary analysis was performed to explore a conceptually new bridge design ; and construction system that may be considered as a candidate for rapid replacement/construction of bridges with ; similar geometric design standards governed by comparable traffic conditions and site characteristics. ; Major technical issues addressed in this study include: 1) identifying existing literature on rapid bridge ; replacement/construction techniques developed worldwide; 2) finding current state-of-practices of rapid bridge ; replacement/construction in the United States; 3) developing a decision-making procedure for justifying the use of rapid ; bridge replacement/construction techniques over the conventional bridge construction methods; and 4) exploring a new ; conceptual bridge design and construction system that supports rapid construction. This report provides both technical ; and non-technical information. Some readers may wish to skip over the analysis details and focus on broader concepts of ; the analysis strategy.
