PIARC Prize "Sustainable Development" - Adapting Road Network Design, Maintenance and Operations Documents to the Realities of Climate Change

Through freeze/thaw cycles, temperature gradients, flooding and storms, climatic conditions regularly affect the state of transportation infrastructure. In order to reduce vulnerabilities in this sector, facility management practices are based on a set of design, maintenance and operations references that incorporate a broad array of climate parameters. Despite the substantial efforts expended globally to limit greenhouse gas emissions and prevent the planet from heating by more than 2°C, several emerging trends are nonetheless being anticipated, like a longer heat wave season, rising sea levels and altered precipitation profiles. Risks to infrastructure will thus evolve as climate change runs its course: it is essential for facility managers to revise their reference materials accordingly!
