AbstractThis paper presents a comprehensive approach to life cycle cost analysis of reinforced concrete bridges that takes into account all costs incurred by the owners and users during construction, maintenance rehabilitation and replacement. This approach provides also an estimate of the environmental impacts associated with construction and replacement of bridge decks in terms of greenhouse gas emissions and waste production. The analysis considers all the key stages in the life cycle, which include extraction of raw materials, construction, maintenance, repair and rehabilitation, replacement, and disposal. The total life cycle costs are evaluated by using the present value method. In this paper, the long-term economic efficiency of high performance concrete (HPC) containing supplementary cementing materials for the construction and rehabilitation of concrete bridges is evaluated and compared to that of normal performance concrete (NPC) in terms of service life, life cycle cost and environmental impacts.
