ABSTRACT
In the arena of infrastructure asset management, the increasing demands on infrastructure networks and the current vulnerability of economic climate have motivated transportation agencies to adopt riskbased methodologies. However, the demands on transportation agencies to focus on service and performance delivery, has promoting a shift from the traditional risk concept, which is mainly based on condition-related failures, to a concept that consider failures to deliver network service performance. This shift has created new challenges to agencies, particularly concerning the interface between and in maintenance-related decision processes. We identified those challenges in a study performed in the context of the Dutch transportation agency Rijkswaterstaat. We conclude that to minimize or overcome those challenges transportation agencies need to address the needs of maintenance-related decision processes to more structured and consistent riskbased asset management methodologies.
