Abstract

This chapter discusses a case study of the field assessment through visual inspection and load testing of a reinforced concrete bridge with cracking caused by alkali-silica reaction, the viaduct Zijlweg. The first main topic of this chapter is the preparation, execution, and post-processing of the load test, through which it could be demonstrated that the capacity of the viaduct is sufficient and structural strengthening is not required. The second topic is a discussion of the cost-savings (economic, environmental, and social) that are obtained through this procedure as compared to a replacement of the superstructure.
