Winter Serviceability in PIARC Member Countries

This article is taken from the general report of the Winter Maintenance Congress held in Tampere (Finland) on 25–27 February 1986, published in the journal Routes/Roads No. 259, second quarter 1986. At its creation in 1965, the Committee dealt solely with winter serviceability. Since the 1975 World Congress, held in Mexico, it has become concerned with all aspects of maintenance and serviceability, apart from specific problems concerning pavements which are examined in detail by the Technical [...]

Cost-Effectiveness Analysis of GHG Reduction Technologies for Steel Bridge Construction And Maintenance - Chambéry 2026 Honourable Mention - Decarbonisation

In Japanese steel bridge construction projects, multi-faceted approach methods have been gradually applied, including material-based reduction through environmentally conscious steel materials and fuel-based reduction using renewable energy and biofuels as measures during the construction stage. Additionally, longevity technologies are applied during construction to improve the durability of steel bridges, which is expected to reduce the number of repairs and reinforcements throughout the lifecycle, [...]

Overall Assessment of the Physical Vulnerability of the French National Road Network to the Impacts of Climate Change - PIARC Honourable Mention - Adaptation to Climate Change

Climate change poses a growing threat to transport infrastructure, particularly road networks, which are increasingly exposed to extreme weather hazards, such as heatwaves and flooding. In response to this challenge, France adopted its third National Climate Change Adaptation Plan (PNACC 3) in March 2025.

Extending the Longevity of Pothole Repairs Development of a Water-Activated Asphalt Primer - Chambéry 2026 Honourable Mention

Pavement damage has become increasingly frequent on expressways in Japan, primarily due to the growing impacts of climate change. In summer, ambient temperatures can exceed 40 °C, causing asphalt pavements to suffer from rutting and blistering. During winter, infiltrated water penetrates the pavement structure and undergoes repeated freeze-thaw cycles—freezing at night and thawing during the day. 

Review of the 17th World Congress on Road Winter Service, Resilience and Decarbonisation

This document provides a brief summary of the 17th World Congress on Road Winter Service, Resilience and Decarbonisation, held in Chambéry from 10 to 13 March 2026. As written proceedings have not yet been produced for all technical sessions, this text focuses primarily on the organisation of the Congress and its key figures. A general report, incorporating contributions from all sessions, will be published at a later date.
