Aluminium Extrusion Bridge Rehabilitation System
Abstract The deterioration of road bridges is becoming a serious problem in Sweden. An increasing number of bridge decks are in such poor condition that they must be replaced. This is due mainly to a severe climate, the use of road salt in winter time, and increasing traffic volume and loads. In certain cases major reinforcement of bridge foundations or replacement of bridges has been called for to guarantee safety, often at great cost. A system is described for replacing damaged bridge decks. The system utilises an orthotropic plate that consists of hollow aluminium extrusions fitted together by tongue and groove. Major reduction of dead loads is achieved which allows increased traffic loads without reinforcing foundations or the structural system.
