| Research Abstract |
In this study, heat and moisture balance models was developed to predict the road surface temperature and snow and ice conditions on a road that is subject to the thermal effects of vehicles and salting (hereafter referred to as vehicle model and salting model). To evaluate the validity of the proposed models, we compared experimental results with calculated results.
As a result, the road surface temperature under dry condition and the thickness and density of snow/ice layer on road calculated by the vehicle model were in good agreement with the measured ones. The road surface temperature and the salt concentration calculated by the salting model were in good agreement with measured ones for both freezing and melting processes.
The proposed model made it possible to calculate the road surface temperature and the snow/ice conditions on the road taken into consideration the thermal effects of vehicles and salting.
