The World Winter Service and Road Resilience Congress is a world-class event that builds on decades of PIARC experience. It brings together road experts and practitioners from across the globe. This is the XVI^th edition of the International Winter Road Congress, which PIARC has organised every four years since 1969.

Historically, this Congress represents a unique opportunity to discuss in depth all subjects related to roads in winter: traffic management, pavement conditions, de-icing agents, equipment, information to users, and more. These topics are and remain essential issues for many PIARC members.

The XVI Congress in 2022 opened a new and exciting chapter for PIARC. In an effort to highlight issues of paramount importance to our members, the additional pillar of resilience was explored during the 2022 Congress. Ensuring the resilience of roads and of transport services is indeed a priority for our members, who are confronted with deteriorating infrastructure, budget constraints, adverse climate events, and rapidly evolving user expectations. Road resilience has been addressed in the broadest sense, without seasonal constraints.

This is why the 2022 Congress was relevant for all countries with two complementary themes:

• Winter service
• Resilience
