Noise-reducing design

To reduce noise emissions due to passing traffic in the VS-JS/R series of single-profile roadway expansion joints, the gap between the edge profiles is covered using sinusoidal finger plates.

Plates with different finger alignments are used depending on the direction of movement of the superstructure. The reduction in the required weld seams compared to the previous version of the cross-section considerably reduces the internal stresses in the component that result from the welding process.
