A sheet-like reinforcement is then placed above the regions of the concrete deck which have a tension of their upper surface, for example those situated above beams. Then, adhesive is applied again and covered with a plurality of second panels, which are similar to the first panels. Finally, the pavement layer is reinstalled.
