Public Private Partnership Approach to an Integrated Life-Cycle Management of Highway Infrastructure in Hong Kong

Transport infrastructure system is central to economic activities and important to economic growth. The rapid economic growth of Hong Kong, especially in last two decades, leads to high demands of a comprehensive and effective highway networks. Conventional procurement approach without the integration of probabilistic life cycle cost model induces substantial long term maintenance cost. The main idea of this paper is to develop a research framework for predicting the service life by using appropriate corrosion deteriorating model on reinforced concrete structures. The deteriorating model will then be integrated into life-cycle cost analysis in dealing with long term maintenance and repair strategy. Once deteriorating and life-cycle cost models of highway structures have been established, proper public private partnership procurement strategies and associated financing method and project period determination could be established.
