Abstract: |
In order to preserve the environment and save resources, Austrian Railways ÖBB have decided to recycle material excavated from contract KAT 2 of the 32.9 km long Koralm Tunnel and process it as aggregates for concrete production. This leads to a saving of gravel resources, reduction of transport routes and reduction of the required landfill areas. The rock mass, which is predominantly formed of schistose gneisses and gneisses with inclusions of mica schist, amphibolites and marbles, is being bored by tunnel boring machines. The material excavated from the tunnel is being recycled on site by processing for concrete aggregates. |
