New polymers for water-permeable concrete tracks -the Bebenroth Tunnel project

摘要

While construction work was underway on the new tunnel for the railroad line from Goettingen to Bebra, Deutsche Bahn came across concrete that is able to drain away thousands of litres of water in just a few minutes and provide a road that swallows up tyre noise. The company modified its plans for the accessibility of the ballast-less track inside the tunnel, which is designed to afford quick and safe access for rescue vehicles and fire trucks hurrying to the scene of an accident. The Bebenroth Tunnel was put into commission earlier this year and, with it, the polymer-modified, open-pored concrete.
