Abstract

Culverts are essential elements of any railway infrastructure. Although there are
commonly a large number of these elements in any transport infrastructure, its
proper maintenance is often treated as a secondary issue when it comes to the
management of ordinary maintenance investments. The aim of this work is to
present a methodology intended to create strategies for prioritizing investments
in culvert maintenance works. Applying risk assessment techniques, a preliminary
diagnosis of the current culvert condition can be obtained, evaluating failure
probabilities and quantifying socioeconomic impacts. At the same time, common
pathologies and general risk factors are identified in order to determine the
optimal solutions to the culvert current issues. Assessment of all culverts in a
transport network allows to efficiently managing the investments in ordinary
maintenance, optimizing the expenses and minimizing risks.

Keywords: culverts, infrastructure maintenance, risk assessment, investments optimization
