Icing Problems on Road and Mitigation Methods in China

Icing problems on roadway are very common in cold regions. It binders traffic and causes traffic accidents, and also damages roads after it thawed in spring breakup period. Many measures, such as blind ditch, pit for containing ice, ice fence/wall, insulated drain etc., have been used. But they were not always effective. This paper introduces the icing problems in China and presents two engineering practices on mitigation icing problems on road in seasonal frozen soil regions and permafrost regions respectively. The seasonal frozen soil regions are in the west of China (high elevation cold regions) and the permafrost regions is in the northeast of China (high latitude cold regions). Two methods of mitigating the icing problems on road are introduced. They are the blind ditch and the multi-outlets drainage system. The blind ditch was used in seasonal cold regions and the key is the imbedded depth of the ditch. The multi-outlets drainage system method was applied in the permafrost regions and the key of this method is the multi-outlets and the good cooperation among all the components of the system. Results show that they were effective on mitigating icing problems on road.
