摘要

Road networks are classified as critical infras-tructure systems.Their loss of functionality not only hin-ders residential and commercial activities,but also compromises evacuation and rescue after disasters.Dealing with risks to key strategic objectives is not new to asset management,and risk management is considered one of the core elements of asset management.Risk analysis has recently focused on understanding and designing strategies for resilience,especially in the case of seismic events that present a significant hazard to highway transportation networks.Following a review of risk and resilience con-cepts and metrics,an innovative methodology to stochas-tically assess the economic resources needed to restore damaged infrastructures,one that is a relevant and com-plementary element within a wider resilience-based framework,is proposed.The original methodology is based on collecting and analyzing ex post reconstruction and hazard data and was calibrated on data measured during the earthquake that struck central Italy in 2016 and collected in the following recovery phase.Although further improve-ments are needed,the proposed approach can be used effectively by road managers to provide useful information in developing seismic retrofitting plans.
