Development of an innovative composite deck slab for railway bridges.
In the past railway bridges were often built without a ballast bed. More and more of these bridges are reaching their calculated end of life. Modern deck slabs of railway bridges usually have to contain a ballast bed, for example for noise protection. This results in an increase of the required construction height for the superstructure. By the replacement of old railway bridges it is often a decisive constraint that the height between rail level and the lowest line of the structure remains equal. In order to fulfil this criterion an innovative and extremely slender composite deck slab was developed.
