This bridge in Biel area was inspected in collaboration with VSL. The goal of this study was to assess the condition of the bridge deck and the PT system present within the beams.
Our analysis showed that the areas with a potential higher corrosion risk, where concentrated above the piles where stresses are higher. Also, it was detected that chloride accumulate along the cables and migrate along it until reaching a low point.
This example illustrates how cables act as a guide to the chlorides migration within the beams of a structure.
