Title:
Abstract:	Lebenszyklusbetrachtungen spielen bei der Bewertung der Nachhaltigkeit von Bauwerken eine besondere Rolle. Sie fokussieren nicht nur auf die einmaligen Umweltwirkungen und die Investitionskosten bei der Herstellung von Bauwerken, sondern ermöglichen die ganzheitliche Beurteilung der fortlaufend anfallenden ökologischen und ökonomischen Wirkungen. Mit der Untersuchung von zwei Autobahnbrücken und zwei Überführungsbauwerken wird das Ziel verfolgt, einen einheitlichen Durchschnittswert für die ökologischen und die ökonomischen Wirkungen von Brückenbauwerken zu definieren. Der Beitrag befasst sich mit der Festlegung derartiger Referenzwerte und stellt erste Lösungsansätze zur Berücksichtigung des Recyclingpotentials von Materialien vor. 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.
