LCA-analyse av en ny, glassbasert vann- og frostsikringsløsning i tunnel

This master thesis addresses some opportunities of reducing the environmental impacts when planning and construction of a road tunnel. It includes a LCA for two different approaches of tunnel lining; a new solution of cellular glass boards (Foamrox) compared to a traditional concept of PE-foam and shotcrete. The case study is Torsbuåstunnelen in Arendal, Norway. The conducted LCA are in accordance with ISO 14040/44 standards and focus on greenhouse gas emissions associated with the material extraction, production of materials and transportation to site. Operation and maintenance of the solutions are not included. The lifetimes of the solutions are not calculated, due to lack of information …
