  • Integration of New Technologies in Winter Service - A PIARC Technical Report

    The purpose of the technical committee PIARC is to share knowledge. The technical committee Winter Service has been handling new approaches that can help perform road maintenance in winter conditions more effectively, environment friendly and with focus on users’ needs. In the cycle 2012-2015 the final report “ADVANCED TECHNOLOGY FOR DATA COLLECTION AND INFORMATION TO USERS AND OPERATORS” was devoted to mutual communication and its further development. The next cycle ended 2015-2019 brought [...]

  • Survey on Winter Maintenance in the City - Collection of Case Studies

    While winter maintenance in rural areas is a relatively well-known topic, it is less so in urban areas, although there are more and more presentations on this topic at PIARC winter maintenance conferences and a specific winter maintenance theme is proposed. Compared to rural roads, winter maintenance in cities is different in many ways. Different modes of transportation, lack of space for snow, often very narrow roads, and development make winter maintenance planning complex. The many responsible [...]

  • Snow And Ice Databook 2022 - Technical Report

    Winter service is the fight against snow and ice on roads to ensure accessablity and traffic safety. One needs to get to work from home, children need to get to school and with very tight procution plans, goods need to arrive in time for the whole process to work. Unpassable roads due to snow and ice would have dramatic effets on all of us as we relate on safe roads. No winter is like the other, weather can change rapidly and can´t be forecasted over longer periodes. Consequently, winter maintenance [...]

  • The Snow and Ice Data Book 2018

    Even though climate change is closely associated with global warming, under the present circumstances it also translates into more extreme weather events. This effect can result in a very mild winter one year followed by a frigid and snowy season the next. Consequently, winter maintenance is very difficult to manage given a context of ever-increasing mobility and declining budgets. We must continue to do our best but with less money. Road network managers must ensure infrastructure remains open [...]

  • International Development of Application Methods of De-icing Chemicals - State of the Art and Best Practice - Technical report

    Fighting snow and ice on roads with de-icing chemicals is a major task in winter maintenance. On the main road network usually sodium chloride is used all over the world. Various studies and practical experiences have proven the high efficiency of sodium chloride treatments on traffic safety and national economy. The application methods have been enhanced worldwide in the recent few years. Pre wetted salting and applications of only brine are more and more established on roads and also on bicycle [...]
