Approximately 63 percent of all bridge surfaces on federal highways in the Federal Republic of Germany consist of prestressed concrete built since 1950. In a short period of time a large volume of work has been accomplished using a new method of construction. Most of the structures meet fully all serviceability, durability, and functional standards with an acceptable maintenance outlay. A few negative experiences could, however, not be avoided. Their causes were faults in design and construction, as well as weak points in the technical regulations, which formed the basis for the design. This report describes the construction principles used in prestressed road bridges, the faults and damage that occurred, and the measures taken to avoid them.
