PIARC events

PIARC (World Road Association) regularly organises international exchanges on technical topics around the world: international seminars in low- and middle-income countries, and workshops in higher-income countries.

PIARC also organises major congresses every four years: the World Road Congress and the International Winter Road Congress.

These exchange opportunities are open to all, upon registration.

In addition, the Association's Committees and bodies also meet very regularly to share knowledge among members. These meetings are not open.

At national level, PIARC National Committees organise meetings and seminars, which allow knowledge to be shared among experts from the country.

Finally, the Association also participates in events organised by other organisations in order to share experiences and develop its partnerships.
