First German railway bridge with UHPC

Using Ultra High Performance (fibre-reinforced) Concrete, or UHPC, made it possible for a railway bridge to be built over the Dürnbach River within a few days. With a comparably light pre-fabricated component, replacing only the superstructure and maintaining the historic abutments was possible. This avoided any long periods of new construction. During construction of the innovative pre-fabricated component, the UHPC compound “Effix PLUS” from HeidelbergCement was used.

The bridge over the Dürnbach River dates back to 1882. It was restored for the first time at the end of the 1920s. The small railway bridge will now go down in history as a pilot project for concrete construction in Germany, as the old bridge superstructure has been replaced by a pre-fabricated component made from high performance concrete. This construction design stops the need for any full new construction, which would have been a slow process. Compared to a conventional solution, this bridge construction also has a significantly lower construction height. This therefore met the...
