In high latitude regions, the moisture dynamics in road systems is more complicated due to freezing/thawing. A better understanding of moisture dynamics in road systems in cold regions is essential for a stable road structure design and also for a sustainable road hydrologic environment. An observation system was installed in a highway in Sweden to detect water, heat and solute dynamics during wintertime. In this study a model approach considers coupled transport of water, heat and solute during freezing/thawing in unsaturated media showing the importance of the wintertime phase change.
