Background
Accelerated Bridge Construction (ABC) has received significant research attention in recent years. For the most part, these research endeavors have focused on means and methods for decreasing impact to the traveling public during new bridge construction. At the same time, there are great opportunities to reduce traffic impacts by decreasing construction time associated with bridge rehabilitation. Most bridges undergo several small and one or two major rehabilitations during their useful lives and decreasing the traffic impacts during these events could have significant benefits. Fortunately, many of the new construction concepts may be able to be adapted for use in rehabilitation scenarios. In still other cases, new means and methods may be needed. This research will complete a synthesis of available rehabilitation alternatives and solutions that could be used by practitioners to complete rapid rehabilitation projects. In some cases these alternatives will be adaptations of new construction methods and in others they will be strictly for rehabilitation activities. This document will provide a comprehensive summary of available solutions. Where appropriate, design and construction procedures will be provided.

Scope
The conduct of this synthesis will be conducted following the general procedures utilized by the National Cooperative Research Program. Specifically, the research team will collect information (Task 1), synthesize it (Task 2), and prepare a written report (Task 3).
