Decision-makers, technical experts, road authorities and managers, operators, equipment manufacturers and engineers, and academics are invited to participate in the Congress.

The Congress, which will be held in English, French and Spanish, will provide a platform where social experiences, chats and online meetings will be held. In addition, attendees will find an information zone and an interactive exhibition area. This will be an accessible virtual experience, designed to facilitate the attendance of participants how and from where they want.

The XVI World Winter Service and Road Resilience Congress

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 will be the 16th 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 will begin a new and exciting chapter for PIARC. In an effort to highlight issues of paramount importance to our members, the additional theme of resilience will be addressed 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 will be addressed in the broadest sense, without seasonal constraints
