PIARC publications from 2024 - 2027 work cycle

This page presents the technical reports of the 2024-2027 work cycle of PIARC (World Road Association). They are available in one or more of the three working languages of the Association which are French, English and Spanish and have been published after a meticulous validation and quality control exercise.

These reports will be published as they are drafted by our Technical Committees, which work according to the objectives set out in the Strategic Plan 2024 - 2027. Reports from the previous work cycle are available on this page.

This follows the structure of the 2024 - 2027 Strategic Plan.

  1. Strategic Theme 1 - Road Administration
  2. Strategic Theme 2 - Road Mobility
  3. Strategic Theme 3 - Safety and Sustainability
  4. Strategic Theme 4 - Resilient Infrastructure

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.
