Speedy Replacement of Expansion Joints thanks to MMBS and “Box in Box” System
Hamburg. On the elevated Elbmarsch road in Hamburg, which is one of the expressway sections with the highest traffic density in Germany, an expansion joint had to be replaced over the total width of the carriageway. In order to reduce the impact on the traffic flow to the extent possible, the subcontractor employed the MAURER “MMBS” which refers to the MAURER Modular Bridging System. This system facilitates the crossing of the job site and ensures a fast switch between “job site mode” and “traffic mode”. The expansion joint was then installed with the so called box in box procedure, thus saving time consuming operations into the bridge structure.
