Bridge Deck Waterproofing on Steel

Bridges are critical structures for infrastructure. ISO 12944, 1-8, is the worldwide recognized standard for corrosion protection of structural steel and is also valid for bridge structures. The 8 parts of this standard cover different items, however parts 2 & 5 are most important for preservation, but it’s difficult to find standards for the protection and refurbishment of bridge decks. Bitumen based state of the art systems cannot fulfil the increasing requirements for modern bridges, when it comes to extended service life and resistance to severe stresses, so developing new resin based systems which can provide a longer service life, shorter down times in case of maintenance works and reduced repair costs are the main target for system manufacturers. The introduction of 2new systems, with excellent physical properties, is shown in this paper.
