Book Description
This synthesis will be of interest to state Departments of Transportation (DOTs) geotechnical, structural, roadway design, construction, and maintenance engineers; DOT research staff; and personnel in local transportation agencies. This synthesis describes the current state of the practice for the design, construction, and maintenance of bridge approaches to reduce, eliminate, or compensate for settlement at the bridge/abutment/embankment interface or the bump at the end of the bridge. It discusses the geotechnical and structural engineering design and procedural factors to reduce the bump at the end of the bridge, and includes numerous illustrations. This report of the Transportation Research Board presents data obtained from a review of the literature and a survey of the state DOTs. It is a supplemental update to Synthesis of Highway Practice 159: Design and Construction of Bridge Approaches (1990). The synthesis identifies and describes techniques that have been used to alleviate the problem of the bump at the end of the bridge including the location and cause of settlement and methods used to reduce settlement. In addition, the types of interaction between various divisions of the DOTs in the design, construction, and maintenance of bridge approaches are addressed.

Book Description
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.

Book Description
Differential settlement at the roadway/bridge interface typically results in an abrupt grade change, causing driver discomfort, impairing driver safety, and exerting potentially excessive impact traffic loading on the abutment. Bridge approach slabs are used to keep the effects of this differential settlement within tolerable limits. In many cases, however, the final magnitude of settlement exceeds the working range of an approach slab, necessitating costly roadway and slab repairs. Many state DOTs regard the settlement of bridge approach slabs as a substantial maintenance problem. Guidelines affecting the use, design methodology, material specifications, and construction techniques vary greatly from state to state. The purpose of this study was to provide a literature review on the subject and to conduct a survey on the state of the practice. Thirty-nine state DOTs responded to the survey. Summary findings were compiled, and a comparison with current VDOT practices was made. Recommendations for a new set of guidelines, aimed at mitigating bridge approach settlement, were formulated.

Book Description
TRB's National Cooperative Highway Research Program (NCHRP) Report 543: Effective Slab Width for Composite Steel Bridge Members examines recommended revisions to the American Association of State Highway and Transportation Officials' specifications for the effective slab width of composite steel bridge members. The report's recommended specifications are applicable to all types of composite steel bridge superstructures and are suitable for design office use. Accompanying CRP-CD-56 contains extensive supporting information, including the recommended specifications and design examples.
