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 comprehensive collection “INTERNATIONAL DEVELOPMENT OF APPLICATION METHODS OF DE-ICING CHEMICALS – STATE OF ART AND BEST PRACTICE”, that described trends especially in the field of de-icing materials.
 In 2023, another cycle of 3.2. Winter service Technical Committee has come to its end. There were various topics discussed in frame of working group “3.2.1 INTEGRATION OF NEW TECHNOLOGIES IN WINTER SERVICE”. This time there was no key issue, however, interesting experience from diverse themes and countries have been discovered. As a result of this effort, this collection of case studies has been gathered. On the following page, you can read some examples of progressive approach in the winter service technology. Nine case studies from six countries create a short excursion to modern maintenance attitudes. We hope they will bring you inspiration and new ideas. At the beginning of each study, author’s email address is added to further contact, if useful.
