Influence of aggressive environmental actions on bridge structures

Bridges represent important part of the roads and railways due to their key and strategy position in transportation infrastructure. During years of exploitation, several degradation processes and additional influences like increment of environmental load attack the bridge structures. Due to those effects, their durability and reliability are decreasing depending on time, which need to be observed during inspections to maintain public safety. This article brings information about influence of aggressive environment on bridges, especially corrosion, which negatively affect serviceability and remaining lifetime of structures, also with results of long-term experimental measurements corrosion phenomena.
