This synthesis on underwater bridge maintenance and repair will be of special interest to bridge maintenance engineers and others involved with repair of bridge elements located below the waterline and in the splash zone. Procedures for correctly assessing the problem and engineering the repair within the constraints of individual situations, including bridge scour considerations, are described. Protection, maintenance, and repair of concrete, masonry, steel, and timber bridge foundation elements are also addressed. This synthesis updates the maintenance and repair portion of NCHRP Synthesis 88: Underwater Inspection and Repair of Bridge Substructures. This report of the Transportation Research Board identifies and describes current practices and innovative repair techniques for problems associated with settlement, scour, and deterioration of underwater bridge elements. The synthesis considers various types of protection, maintenance, and repair work on bridge substructures, both underwater and in the splash zone, and includes techniques, and their effectiveness. Current research in the topic area and critical research needs are also identified. A limited bibliography is also provided.

This manual is intended to serve as a reference for design engineers, construction inspectors, resident engineers, inspection divers and other administrative and technical staff whose work tasks include the repair or rehabilitation of elements of bridges or similar structures located below water. The manual addresses a variety of design and construction issues that must be considered in determining the feasibility of, and selecting the repair or rehabilitation methodology, for underwater projects. This information can aid in developing cost effective and durable repair and rehabilitation designs.

Road and bridge networks in OECD countries are ageing and substantial funds are needed for repair and rehabilitation. Underwater or underground damage to bridge substructures is often invisible, inaccessible, and hard to assess. A variety of measures and technologies for bridge substructures has proven practically effective despite difficult geological and environmental conditions. This report catalogs actual damage and defects of bridge substructures and provides several examples of inspection, repair, and strengthening technologies. It proposes measures to protect investment capital while insuring low operational costs. It is a resource book for policy makers and administrators responsible for bridge management.
