Abstract
The practices of bridge management tend to be poor in local municipalities due to budget limitation as well as lack of in-house engineers. Thus, it is not realistic to expect that all jurisdictions work the best-shot asset management being equipped with deterioration forecasting and life cycle cost evaluation. Instead, it is more feasible and plausible to develop a profiling methodology for their bridge management; bridges are categorized into a few groups based upon bridge and failure characters, and maintenance and rehabilitation strategies are standardized for the respective bridge groups. In this paper, the heterogeneity in deterioration speeds is investigated made by use of mixed Markov deterioration hazard model, and a systematic methodology is presented to profile bridges maintenance strategies with reference to differences in deterioration speeds. A case study conducted for national highways in Kinki region is also illustrated in the paper.
