During the renovation, the concrete bridge-deck was designed to work with the steel elements as a composite structure. The composite structure requires keeping the level of shrinkage of the concrete deck low.
The Concrete Division of Sika Hungary Ltd. recommended two different solutions. To select the best solution, the structural engineers undertook a preliminary examination by the Department of Construction Materials and Engineering Geology of Budapest University of Technology and Economics (BME).
