Application of ECC for bridge deck link slabs

In this article, the application of ECC in a bridge deck link slab is described. The unique ultra high tensile ductility and tight crack width of selfconsolidating ECC is exploited in this application to improve bridge deck constructability, durability, and sustainability. Design guidelines and material specifications were developed for implementation of this ECC link slab technology. A construction project implementing these guidelines and specifications was conducted in 2005 on an ECC-concrete bridge deck in southeast Michigan, USA. This article summarizes the experience of this project.
