Abstract: |
Ever more stringent requirements have been specified in recent years for the surfaces of tunnel inner linings with regard to surface porosity (with influence on the ease of cleaning) and lightness. These requirements are normally fulfilled by filling and applying tunnel paint. Recently there have been many cases of damage to paint or coating systems, sometimes only a few weeks after opening for traffic. This often includes the separation of the coating. This flaking leads to increased dirt adhesion and thus to a reduction of lightness and irritation to the field of view of the drivers. The refurbishment work, which is often necessary, leads to traffic obstruction like hold-ups and diversions. For this reason, the durability of the surface is of great significance, and innovative solutions are also being investigated in the field of concrete technology. The following article presents an alternative and durable method of fulfilling all the requirements placed on the surface of the tunnel inner lining. |
