A study towards the application of Markovian deterioration processes for bridge maintenance modelling in the Netherlands

Infrastructures in the Netherlands are rated according to a discrete condition scheme and the results are registered in an extensive database. The paper discusses the application of a continuous-time Markov process for modelling deterioration and introduces new results for optimizing periodic inspections and preventive maintenance. The focus of this discussion is on the condition of superstructures of concrete highway bridges in the Netherlands for which 19 years of inspection data are available.
