A study on optimization of salting by estimation of sliding friction coefficient on road

在这项研究中，热湿平衡模型的开发，以预测路面温度和冰雪条件的道路上，是受车辆和盐渍的热效应（以下简称为车辆模型和盐渍模型）。为验证所建模型的有效性，将试验结果与计算结果进行了对比，结果表明，车辆模型计算的干燥条件下路面温度、路面积雪厚度和密度与实测值吻合较好。在结冰和融化过程中，盐渍化模型计算的路面温度和盐浓度与实测值吻合较好，该模型可用于考虑车辆热效应和盐渍化的路面温度和冰雪条件的计算。

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.
