Study on the Influence of Ice and Snow on Pavement Evaluation

摘要

The study analyzed mountainous highway operation safety factors from the road environment, traffic environment and climate factors. Utilizing the indoor test to measure the friction coefficient of ice and snow road, summarize the changing trends of friction coefficient which was compared with accident rates, and then establish the model of friction coefficient and accident rate. A model of the vehicle under snow environment was put forward. The study deeply analyzed the influence of snow and ice weather on the roadpavement;it can provide technical support for highway of seasonal frozen area dealing with ice and snow weather.
