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

本研究建立了热湿平衡模型，用于预测受车辆和盐渍热效应影响的路面温度和冰雪状况（以下简称车辆模型和盐渍模型）。为了评估模型的有效性，我们将实验结果与计算结果进行了比较。结果表明，车辆模型计算的干燥工况下的路面温度、路面冰雪厚度和密度与实测值吻合较好。在冻结和融化过程中，模型计算的路面温度和盐浓度与实测值吻合较好。提出的模型可以计算考虑车辆和盐的热效应的路面温度和路面冰雪状况。

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.
