A guide to inspecting, maintaining, and rehabilitating various types of concrete and composite bridges. It also discusses emergency measures you can take to keep bridges operating safely until they can be rehabilitated. It provides civil and structural engineers with methods for conducting safety inspections, condition surveys, and more.

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.

This guide provides bridge related definitions and corresponding commentaries, as well as the framework for a systematic approach to a preventive maintenance program. The goal is to provide guidance on bridge preservation. This guide is intended for Federal, State, and local bridge engineers, area engineers, bridge owners, and bridge preservation practitioners.

An Insiders' Guide to Inspecting, Maintaining, and Operating BridgesSuspension bridges are graceful, aesthetic, and iconic structures. Due to their attractiveness and visibility, they are well-known symbols of major cities and countries in the world. They are also essential form of transportation infrastructure built across large bodies of water. D

More than a third of America's bridges are considered substandard--either structurally deficient, functionally obsolete or both. Offers first-rate, practical guidance regarding the inspection and rehabilitation of aging bridge infrastructure including all elements involving structure, various materials and design types. Features seismic retrofit and coverage of environmental issues. Each chapter is written by an authority on the subject. Contains top-quality, detailed line illustrations plus photographs of actual rehab projects.

Highway departments around the world are faced with the dilemma of providing improved operations on a "shoe string budget". Even after the much needed infrastructure funding is received, the question of which project comes first must be answered. Written by a 20-year veteran with the Kansas Department Of Transportation Bridge Office in design and in maintenance. Highway Bridge Maintenance Planning and Scheduling provides Senior Bridge Maintenance Engineers or "Senior Squad Leaders", practical advice for creating an effective maintenance program that will allow them to not only plan, schedule, direct and monitor highway bridge repair and rehabilitation project but also evaluate all completed work for technical acceptability, productivity and unit-cost standards. Provides the tools and methods for building and maintaining and effective maintenance planning and scheduling organization Provides experience-based suggestions for evaluating highway bridges and determining maintenance priorities Methods for evaluating all completed work for technical acceptability, productivity and unit-cost standards.

In the last two decades, the rapid deterioration of bridge structures has become a serious technical and economical problem in many countries, including highly developed ones. Therefore, bridge rehabilitation has also become a very essential factor (sometimes even a decisive one) in contemporary bridge engineering. The book covers in synthetic form nearly all the most important problems concerning bridge rehabilitation, such as bridge superstructure and substructure, the typical damage observed in bridges as well as the assessment and evaluation techniques of their technical condition. The book is intended mainly for postgraduate university students. Therefore, all the problems are mostly presented in their physical, chemical and technical as well as economical aspects. The relevant requirements are treated as objective ones, i.e. irrespective of the rules, standards, regulations or guidelines particular to any country. This approach to the subject gives the book a more general character and therefore makes it a useful text for most civil engineering courses./a
