Feasibility study for the reinforcement of a bridge underpass in NRW

As part of the total overhaul of the A3, the 'Landesbetrieb Straßen.NRW' is also involved in work on the Rottbach underpass. Based on an analysis of the existing structure, a new replacement structure was recommended, but this proposal was rejected. A preliminary design for a strengthening option was then suggested, with a 20 cm thick shotcrete shell of steel reinforced concrete as a replacement structure. However, this would cause a considerable narrowing of the cross-section of the structure and high costs for the construction logistics. Within the scope of a feasibility study, different options were examined. These resulted in several carbon reinforced concrete options which could be used as an alternative to the classic strengthening with steel reinforced concrete.
