Thickness of Corrosion Layers on Typical Surfaces of Weathering Steel Bridges

Program of experimental atmospheric corrosion tests carried out on weathering steel bridges in the Czech Republic is briefly introduced in this paper. Attention is paid to the evaluation of corrosion processes on load-bearing structures of girder bridges with the roadway above the supports. The article presents selected results of experimental atmospheric corrosion testing aimed at the measurement of corrosion products thicknesses. It results from the tests that corrosion processes on weathering steels bridges are significantly conditioned by position and location of exposed surface within the structure.
