Book Description
This synthesis reports bridge inspection practices in the United States and selected foreign countries. The synthesis is a collection of information on formal inspection practices of departments of transportation (DOTs). These are primarily visual inspections and they provide data to bridge registries and databases. For U.S. inspection practices, this synthesis reports on inspection personnel, inspection types, and inspection quality control and quality assurance. Staff titles and functions in inspection programs are reported, together with qualifications and training of personnel, formation of inspection teams, and assignment of teams to bridges. Inspection types are described in terms of their scope, methods, and intervals. Quality control and quality assurance programs are reviewed in terms of the procedures employed, staff involved, quality measurements obtained, and the use of quality findings in DOT inspection programs. Foreign practices are presented in the same organization of inspection personnel, types, and quality programs. Comparisons of U.S. and foreign inspection practices are included. Information was obtained from a questionnaire sent to U.S. state transportation departments, similar questionnaires modified individually for transportation agencies in selected foreign countries, and formal documents used by transportation departments and agencies. These documents primarily included bridge inspection manuals, inspection training manuals, and technical memoranda, but also included blank forms for inspections, DOTs job descriptions for inspectors, and descriptions of inspection training courses. Overall, this synthesis includes information from forty U.S. state transportation departments and from roads agencies in eight foreign nations (Denmark, France, Finland, Germany, Norway, South Africa, Sweden, and the United Kingdom). The synthesis also includes, in an appendix, information from a few provincial and municipal transport agencies in Canada.

Book Description
"TRB's National Cooperative Highway Research Program (NCHRP) Report 782: Proposed Guideline for Reliability-Based Bridge Inspection Practices presents a proposed guideline for reliability-based bridge inspection practices and provides two case studies of the application of the proposed guideline. The guideline describes a methodology to develop a risk-based approach for determining the bridge inspection interval according to the requirements in Moving Ahead for Progress in the 21st Century Act (MAP-21)."--Publisher description.

Book Description
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.

Book Description
The traveling public has no patience for prolonged, high cost construction projects. This puts highway construction contractors under intense pressure to minimize traffic disruptions and construction cost. Actively promoted by the Federal Highway Administration, there are hundreds of accelerated bridge construction (ABC) construction programs in the United States, Europe and Japan. Accelerated Bridge Construction: Best Practices and Techniques provides a wide range of construction techniques, processes and technologies designed to maximize bridge construction or reconstruction operations while minimizing project delays and community disruption. - Describes design methods for accelerated bridge substructure construction; reducing foundation construction time and methods by using pile bents - Explains applications to steel bridges, temporary bridges in place of detours using quick erection and demolition - Covers design-build systems' boon to ABC; development of software; use of fiber reinforced polymer (FRP) - Includes applications to glulam and sawn lumber bridges, precast concrete bridges, precast joints details; use of lightweight aggregate concrete, aluminum and high-performance steel

Book Description
Improving bridge safety, reliability, and the allocation of bridge inspection resources are the goals of the proposed risk-based bridge inspection practices. Currently, most bridges in the United States are inspected at a fixed calendar interval of 24 months, without regard to the condition of the bridge. Newer bridges with little or no damage are inspected with the same frequency as older, more deteriorated bridges thus creating inefficiency in the allocation of inspection resources.The proposed methodology incorporates reliability theory and expert elicitation from the Indiana Department of Transportation's Risk Assessment Panel, developed during this research, to rationally determine bridge inspection needs. Assessments are made based on the likelihood and consequence of failure for specific bridge components. The likelihood of failure is determined through attributes based on design, loading, and condition characteristics while the consequence of failure is based on expected structural capacity, public safety, and serviceability. By combining the expressions of likelihood and consequence for each component, an optimum inspection interval for the entire bridge can be determined through the use of risk matrices.The methodology was evaluated through case studies involving Indiana bridges. Over 30 years of historical inspection reports were utilized in the back-casting process to evaluate deterioration levels and assess the adequacy of the risk criteria. Results of the case studies conducted during the research indicated that the risk analysis procedures provided suitable inspection intervals ranging from 24 to 72 months for Indiana bridges.

Book Description
There is considerable uncertainty about what level of traffic loading bridges should be designed for. Codes specify notional load models, generally to represent extreme levels of normal traffic, but these are often crude and have inconsistent levels of safety for different load effects. Over the past few decades, increasing quantities of reliable truck weight data has become available and it is now possible to calculate appropriate levels of bridge traffic loading, both for specific bridges and for a road network. Bridge Traffic Loading brings together experts from all over the world to deliver not just the state-of-the-art of vertical loading, but also to provide recommendations of best-practice for all the major challenges in the field – short-span, single and multi-lane bridge loading, dynamic allowance and long-span bridges. It reviews issues that continue to be debated, such as which statistical distribution is most appropriate, whether free-flowing or congested traffic governs and dealing with future traffic growth. Specialist consultants and bridge owners should find this invaluable, as will regulators.
