Strengthening and Rehabilitation of U-Shaped RC Bridges Using Substitute Cable Ducts

Figure 9

Prestressing tendons composed of individual monostrands (black HDPE sheaths) on the bottom side of the girder after curvature of their trajectories in saddles [21]. After the prestressing of tendons, the bottom side of the girder is provided with the anchored protective concrete cover layer (the second corrosion protection). The appearance and the concrete character of the bridge are then preserved.
