The need for durable traffic bridges in the Netherlands has induced development of a modular building system for bridges so that bridges up to 30m length and 5m width can be built economically with two standard elements: (1) the Railing element and (2) the plate element. All elements are made from UHPFRC and are post-tensioned together to form a bridge. The requirement for the development was to design a bridge with no maintenance for 100 years and to have an economical bridge which does not cost more than the standard existing bridges. FDN Engineering + Construction designed and built the first bridge in Rotterdam with a length of 18.9m and 3.4m width. The deck has a thickness of 60mm and the railing beam has a maximum thickness of 125mm. We achieved a very slender deck by adding traditional reinforcement. The railing was produced with only the fibre reinforcement.
The test loading of the bridge was a uniformly distributed loading of 5 kN/m² and a twelve ton vehicle. The bridge passed the test with excellent results and the calculated deformations were nearly the same as the measured deformations.
