Abstract
The viaduct Zijlweg, a reinforced concrete bridge with cracking caused by an alkali-silica reaction, is the subject of a case study that is examined in this chapter. The preparation, execution, and postprocessing of the load test serve as the chapter’s primary focus. The load test and analysis of measurements showed that the viaduct’s capacity is adequate for the code-prescribed live loads and that no structural strengthening is necessary. The second topic is a discussion of the economic, environmental, and social cost savings gained from this procedure as opposed to replacing the superstructure.
