Abstract:
It is becoming preferable, both environmentally and economically to upgrade bridges rather than to demolish and rebuild them. The deterioration of bridges from environmental influences and from traffic loads require rehabilitation and renewal programs to maintain even current service levels on the bridge infrastructure network. There are increased demands for high durability, longer service life, reduced maintenance cost and cost/performance optimization. Advanced Composite Systems have now become a viable method of strengthening existing bridges worldwide. This paper presents the evolution of carbon fiber systems since 1991, including relevant Test Reports for Bridge Engineering as well as their worldwide application.
