Proceedings of Winter Road Congresses

PIARC (World Road Association) has organized an International Winter Road Congress every four years since 1969.

The International Winter Road Congresses are international conferences that bring together winter road experts from all over the world. They deal with all topics related to the operation and maintenance of roads in severe winter countries.

The XVI Congress in 2022 opened a new chapter with road resilience addressed in the broadest sense, without seasonal constraints, in an effort to highlight issues of paramount importance to our members.

The congress proceedings from 2002 to 2014 are available on DVD, the content of which has also been adapted as websites. Since 2018, the proceedings are exclusively available on dedicated websites.
