MAURER supplies expansion joints, bearings, and dampers for bridge and viaduct projects. One of MAURER's global projects in this area is the Schiersteiner bridge project in Germany. The issue concerned the expansion (temperature) joint and the bearing.
In this bridge project, MAURER supplied both the expansion joint and the bearing. This bridge was first built in 1962. By the 2010s, the intensity of its use had reached 90,000 vehicles per day, so modernization was required.
For this bridge, MAURER supplied spherical bearings capable of withstanding a load of 6,000 tons. The maximum expected displacement ensured by those bearings was determined to be 1.5%. The bearings measure 1600x1500x380 mm, and each weighs 4.6 tons. These figures are 30% more efficient compared to standard bearings. MAURER developed and patented the MSA material for these spherical bearings. It is resistant to corrosion and extreme weather conditions and has a service life of 100 years.
The second product supplied for this bridge was the expansion joint. For this project, MAURER used noise-reducing expansion joints. These expansion joints reduce noise by 40-60% when vehicles pass over them. The MAURER Swivel Expansion Joint allows for displacement in all directions.
The MAURER generator compensator Swivel Expansion Joint allows for displacement in all directions and has a service life of at least 50 years. The longitudinal movement of the compensator varies between 700 to 1100 mm.
