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

在本研究中，建立了受车辆热效应和盐渍影响的路面温度和冰雪状况的热湿平衡模型(以下简称车辆模型和盐渍模型)。为了验证模型的有效性，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条件下的路面温度以及路面冰雪厚度和密度与实测值吻合较好。在冰冻和融化过程中，盐化模型计算的路面温度和盐分浓度与实测值吻合较好，使得考虑车辆热效应和盐渍影响的路面温度和冰雪条件的计算成为可能。

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.
