Abstract:	Life cycle considerations as a base for assessment of the sustainability of road bridges. Life cycle considerations are important for the assessment of the sustainability of constructions. Taking the life cycle into account it is not only possible to determine single environmental impacts and investment costs arising during the construction of buildings, but also to assess the consecutive ecological and economical impacts. The aim of this study was to define a consistent average value for ecological as well as economical impacts of road bridges by evaluating two viaducts and two overcrossings. This article deals with the determination of those reference values and presents an approach how to deal with the recycling potential of materials within the life cycle assessment.
