MAURER supplies expansion joints, bearings, and dampers for bridge and viaduct projects. One of MAURER's global projects in this area is the Baerl Rhine Bridge located on Federal Highway 42 in Germany, connecting the Baerl and Beeckerwerth districts.
The total length of the bridge is 1,030 m, and its longest span is 310 m. It was built in 1990 and consists of 3 lanes in each direction.
Maurer’s main task was to replace the expansion joint on the bridge. To do this, 4 expansion joints were manufactured. The installed XLS 900 and XLS 600 expansion joints allow for the bridge displacement within 855 and 570 mm, respectively. The XLS 900 expansion joint is the heaviest of the 4 joints, weighing 25 tons. The length of each expansion joint reaches 23.15 m.
Since this bridge is part of a highway, replacement required great attention and care. Replacing the expansion joint and installing the new one took 3 months. This included ensuring the safety of the structure, dismantling the old expansion joint, installing new reinforcements and the expansion joint, concreting, and asphalting. The new expansion joint installed does not require maintenance for 40 years.
