Life cycle cost analysis of portland cement concrete pavements

This report describes the development of a new life cycle cost analysis methodology for portland cement concrete pavements — one that considers all aspects of pavement design, construction, maintenance, and user impacts throughout the analysis period. It predicts pavement performance using state-of-the-art performance models and reliability concepts, from which it determines maintenance and rehabilitation needs. Any construction performed on a roadway has associated construction and user costs. Also associated with all highway pavement construction are external costs, upon which it is difficult if not impossible to place a value. This methodology models the effects of construction on all these aspects and, where the effects cannot yet be quantified, allows new models to be added.
