Ulm, B10 Wallstraßenbrücke

Customer: Stadt Ulm
Construction period: 5 months Year of construction: 2022
The entire road surface of the Wallstraßenbrücke B10 Ulm was removed by milling and renovated by means of a quick sealing system HANV (asphalt support structure subsequently filled up), as well as a rolled asphalt road surface.
There was only a period of 3 weeks per lane, during which a surface of about 4,000 m² needed to be treated.
With a traditional sealing system, this construction project would not have been possible in the planned period of time.
For the sealing measures over 75 t of HANV resin were installed in over 400 t asphalt support structure.
