It is common practice that aging and structurally damaged prestressed concrete bridge members are taken out of service and replaced. This, however, is not an efficient use of materials and resources since the member can often be repaired in situ. There are numerous repair techniques proposed by entrepreneurial and academic institutions which restore prestressed concrete girder flexural strength and save both material and economic resources. Of course, not all repair methods are applicable in every situation and thus each must be assessed based on girder geometry and the objectives of the repair scenario. This document focuses on the practical application of prestressed concrete bridge girder repair methods. In this document, repair methods are presented for three prototype prestressed concrete highway bridge girder shapes: adjacent boxes (AB), spread boxes (SB), and AASHTO-type I-girders (IB), having four different damage levels. A total of 22 prototype repair designs are presented. Although not applicable to all structure types or all damage levels, the repair techniques covered include the use of carbon fiber reinforced polymer (CFRP) strips, CFRP fabric, near-surface mounted (NSM) CFRP, prestressed CFRP, post-tensioned CFRP, strand splicing and external steel post-tensioning. It is the authors' contention that each potential structural repair scenario should be assessed independently to determine which repair approach is best suited to the unique conditions of a specific project. Therefore, no broad classifications have been presented directly linking damage level (or a range of damage) to specific repair types. Nonetheless, it is concluded that when 25% of the strands in a girder no longer contribute to its capacity, girder replacement is a more appropriate solution. Guidance with respect to inspection and assessment of damage to prestressed concrete highway bridge girders and the selection of a repair method is presented. These methods are described through 22 detailed design examples. Based on these examples, review of existing projects and other available data, a detailed review of selection and performance criteria for prestressed concrete repair methods is provided. Best practices based on the study objectives are presented.

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.
