AbstractMany of North America's bridges are in urgent need of rehabilitation: nearly one of every three bridges is rated structurally deficient or functionally obsolete. According to a recent survey, the estimated cost of bringing those bridges to an acceptable level of repairs is US$80 billion. Significant discrepancies between claimed laboratory performance and the actual field performance of repair and protection systems for concrete bridges are frequently observed. Field performance is one important criterion for the selection of repair and protection materials, but the lack of comprehensive data and suitable guidelines makes the selection process difficult. To address this probelm, the National Research Council Canada and partners from the private and public sectors have joined effort to investigate the long-term field performance of various repair and protection systems for concrete bridges. This paper presents a brief description of major projects.
