Abstract [en]

The Life cycle assessment (LCA) is a comprehensive framework for analyzing the environmental impact of product or services by considering the flow of raw materials and energy over a life cycle. This paper is a review of the current knowledge associate with LCA of bridge infrastructures, and a case study of the Bollstaån railway bridge is carried out by the LCA analysis. In order to simplify the analysis, the study is performed only on the superstructure including the railway track and the steel section. The result can be further integrated with different bridge design, thus identify the dominant elements in a railway superstructure which contributes significant environmental impact. It has been noticed the concrete consumption contributes the significant impact in the GWP and AP, while for the POCP, the rail production is the major concern. The ballast manufacture, the transportation of concrete and reinforcement has ignorable impact.
