It is estimated that 225,000 bridges, including nearly 40% of highway bridges, in the United States today are structurally deficient or functionally obsolete. While the urgency of this problem has begun to be acknowledged at official levels, and more public funds set aside for bridge inspection and rehabilitation, the need remains for engineers versed in contemporary rehabilitation methods. Unfortunately, until the publication of this book, engineers’ efforts to educate themselves in the field have been thwarted by the fact that good, up-to-date material on bridge inspection and repair could be obtained only through a painstaking search through hundreds of specialized publications. Edited by Louis G. Silano, P.E., Senior Vice President and Technical Director of Structures with the firm of Parsons Brinckerhoff. Bridge Inspection and Rehabilitation: A Practical Guide is the first and only "A-to-Z" guide to practical aspects of bridge inspection and rehabilitation. Comprising contributions from a group of seasoned professionals from around the nation, it provides insights into every element of bridge structure, including broad coverage of materials and design types. Among important topics covered in Bridge Inspection and Rehabilitation are: Advances in inspection techniques, including underwater inspection and non-destructive testing All bridge design types, including suspension bridges, cable-stayed bridges, trusses, moveable bridges, and others Basic structural elements, such as substructures, superstructures, decks, bearings, and joints Special topics of contemporary concern, such as seismic design and seismic retro-fitting, environmental control issues, maintenance of traffic during rehabilitation, repair of historical bridges, and much more Generously illustrated with nearly 200 line illustrations and photographs and offering in-depth coverage of most practical aspects of bridge assessment and repairs. Bridge Inspection and Rehabilitation is an invaluable resource for practicing bridge engineers and contractors.

Evaluation, repair and rehabilitation of bridges are increasingly important topics in the effort to deal with the deteriorating infrastructure. For example, in the United States about 40 percent of the nation's 570,000 bridges are classified, according to the Federal Highway Administra tion's (FHW A) criteria, as deficient and in need of rehabilitation and replacement. In other countries the situation is similar. FHW A estimates the cost of a bridge replacement and reha bilitation program at 50 billion dollars. The major factors that have contributed to the present situation are: the age, inadequate maintenance, increasing load spectra and environmental contamination. The deficient bridges are posted, repaired or replaced. The disposition of bridges involves clear economical and safety implications. To avoid high costs of replacement or repair, the evaluation must accurately reveal the present load carrying capacity of the struc ture and predict loads and any further changes in the capacity (deterioration) in the applicable time span. Accuracy of bridge evaluation can be improved by using the recent developments in bridge diagnostics, structural tests, material tests, structural analysis and probabilistic methods. There is a need for an international exchange of advanced experience to increase the research effi ciency. The Workshop is organized on the premise that the exchange of existing American and European experience in the area of bridge evaluation, repair and rehabilitation is beneficial for both parties involved.
