冰雪路面抗滑特性研究

Study on anti-sliding performance of ice snow covered pavement

针对东北地区冰雪路面抗滑性较差的情况,详细划分了冰路面及雪路面的类型,采用实车试验法和摆式仪法,从温度、构造深度、行车速度以及轮胎胎压等方面,测量了冰雪路面的摩擦系数,指出在冰雪没有完全覆盖路面的情况下,构造深度越小,摩擦系数越低;同时随着车速提高,摩擦系数降低;冰、雪路面摩擦系数均在0℃附近达到最低值,行车安全处于危险状态。

In light of poor anti-sliding performance of ice snow covered pavement in northeast region,the article specifically analyzes ice pavement and snow pavement types,applies real vehicle testing method and pendulum testing method,measures the ice snow covered pavement friction coefficient from aspects of temperature,structural depth,driving speed and tire pressure,and finally points out that： when the pavement is not completely covered with ice and snow,the smaller the structure is,the low the friction coefficient is,meanwhile,the friction coefficient will reduce with the driving speed improving,the ice and snow pavement friction coefficient is near 0 ℃,it will be rather dangerous for driving.
