Praxiserfahrungen zum Verstärken von Betonbrücken

Experiences on the Strengthening of Concrete Bridges

Increasing loads, in particular by heavy-duty traffic, and age-related load-bearing deficits of older bridges result in the need of repairing and strengthening numerous concrete bridges. In order to contribute to a successful realization of future strengthening measures, a collection of experiences focusing on economical and constructive perspectives was provided on behalf of the German Federal Highway Research Institute (BASt). In this documentation [1], an overview is given on the state of the art of strengthening technologies for reinforced and prestressed concrete bridges, and the experiences of 76 strengthening measures are summarized. Representative strengthening measures are presented in anonymized form. This report describes the new documentation [1], and essential experiences of the evaluated cases of application are introduced.
