Paudèze Viaduc

BRIDGES

Pont sur la Paudèze in Lavaux region was a typical “condition assessment before maintenance works” mission. We focussed on the detection of contaminated regions on the bridge deck.

Our analysis showed that the regions with a potential higher corrosion risk, where concentrated above the piles where stresses are higher. Also, it was detected that the waterproofing layer was deficient within the last third of the bridge, it was generated by a breach within the overlap of two waterproofing layers.

The bridge was renovated in 2018, local resurfacing was performed, the waterproofing was changed, and the cantilever was reinforced using UHPFRC (Ultra-High Performance Fibre Reinforce Concrete).
