PIARC publishes numerous technical reports, which are reference documents that are widely used in the road and transport sectors. They complement other publications of the Association such as the Routes / Roads magazine, Proceedings of international congresses, Proceedings of international seminars and online Manuals.

These technical reports are the output of the work of over 1,000 experts during a four-year work cycle. Their involvement and professionalism must be underlined. They are mobilized within Technical Comittees or Task Forces as defined by the Strategic Plan, which structures the activities of the Association and aims to meet the expectations and needs of road administrations and operators and all members of the Association. These reports thus constitute a wealth of information, made available to all. They offer state of the art international best practices on roads and road transport in a context of integrated and sustainable development.

These technical reports are available free of charge as part of the knowledge sharing and dissemination mission that guides the Association. All language versions are presented simultaneously here, to take into account the reading preferences of each user.
