Technical Session 3.2 - Winter Service

Wednesday, October 4 14:30 - 18:00
Chair: Mr Peter Nutz, Chairman of PIARC TC 3.2 on Winter Maintenance, Austria
Room: South Hall 1, 1st floor

PIARCs Winter Service Committee TC 3.2 deals with everything related to winter, snow and ice on the road and how to deal with it.

Ploughing snow and use salt or abrasives sounds much less complex than it is in reality. New types of sensors, weather forecasts, decision support systems, spreading technologies and techniques and much more develop constantly. A good example is the use of liquid de-icing and anti-icing agents which was introduced in many countries around the world.

This session gives an overview of the TCs work in the past cycle as well as selected Presentations representing the development of winter service around the world.
