• Description:
• A key criterion for ensuring the durability of bridge cables is functional external corrosion protection. The top coating on the external corrosion protection of the fully sealed bridges recently became detached Ropes found after less than 20 years of use. This premature damage indicates systematic abnormalities in the corrosion protection system. Without an analysis of the damage currently observed, there is a risk of limited damage Durability of the corrosion protection and thus increased life cycle costs for the building contractors. The aim of this research project is to identify likely causes of damage based on a technical assessment of the damage identified and based on this, to develop a reliable and transferable investigation approach for the future application of rope coatings. The project includes individual studies on specialist questions of a technical nature: the systematic recording and Classification of damage, laboratory tests of the coating systems, analysis of the rope surface and climatic influences as well as the development of a test concept for future applications. The results form the basis for the revision of the technical regulations, in particular the TL-KOR-VVS, the TP-KOR-VVS and the ZTV-ING Part 4-4 and Part 4-5. The benefit of the FE project includes the timely consideration of the research results in the context of upcoming calls for proposals Conservation measures, specifically at the Bremen airport bridge, the Beeckerwerth Rhine bridge and the Neuwied Rhine bridge. This helps to maximize the durability of the renewed corrosion protection systems and the life cycle costs of those affected Optimize bridge structures.
