Service life predictions typically focuses on global conditions of the bridge as well as the local condition of critical load carrying elements that may even result in total collapse of the bridge.  The rapid deterioration of conventional rebars may significantly reduce service of bridge or its component.

A software addressing this problem has been developed mainly focusing on chloride induced corrosion of reinforced concrete structures. The input of the software is concrete cover, type of cement, crackwidth, environmental condition sandage of the structure. The output is the remaining lifetime in years in case of normal deterioration and deterioration due to corrosion.
