N2 - Today, the aged infrastructures has been grown globally, and many types of policy research are actively progressed. In South Korea, roughly 42% of total bridges were built from the '70s to the '90s, and it will make substantial investment costs for infrastructure suddenly. However, many types of research were focused on the future investment cost for new road bridge construction based on historical investment statistics, and the study of large-scale reinvestment cost for old-aged road construction is not sufficiently considered yet. For the reasons, this study suggests a future paradigm for investment cost, including maintenance, new construction, and reinvestment according to the life cycles of the infrastructures. First, to calculate maintenance cost. Second, the reinvestment cost is defined as demolition and reconstruction costs when a bridge has reached the end of its life. To calculate the reinvestment cost, this study used unit cost about the demolition and reconstruction costs using other previous studies.
