HDM-4 is an economic appraisal tool that is used worldwide for assessing different road investment strategies. Typical uses of HDM-4 include a project evaluation where the economic and technical efficiency of the proposed scheme are analysed, as well as preparing annual road work programmes under budgetary restrictions. In the light of climate change and other impacts that may affect pavement performance, it is now more common to determine how resilient the proposed plan of work is to such effects, or to design resilience into HDM-4 prior to the analysis.
This foresight session looks at approaches to address resilient road investment strategies using HDM-4. The session will present case studies where resilience has been addressed by HDM-4 from a number of different countries, as well as take a forward look at how HDM-4 can address this important issue in the future.
