冬季道路结冰,造成路面摩阻力下降,使行车安全受到很大影响。为了能够以低碳、环保的方式解决冬季道路结冰问题,该文提出了一种新的路面结构方式:低模量弹性路面。由力学分析可知,若与冰接触的面层采用超低模量材料,则对于冰层最易破坏点位的拉应变将会提高很多,通过温度、荷载、冰层厚度和弹性铺装层厚度等影响因素的分析,表明在冬季温度低、冰层厚的地区如采用超弹性路面,则能够实现BZZ-100标准荷载下的自破冰;冬季气温稍高、冰层较薄的地区,则能够实现小汽车自破冰。同时通过室内试验验证,低模量弹性路面比沥青基材路面,自破冰效果良好,具有一定的可行性。
Winter road icy, causing the road friction decreased, so traffic safety is greatly affected. In order to solve the problem of icy road in winter in a low-carbon and environment-friendly way, a new way of pavement structure is proposed: low modulus elastic road surface. From the mechanics analysis, we can see that if the surface layer in contact with ice is made of ultra-low modulus material, the tensile strain will be greatly increased for the most vulnerable ice layer. Through the temperature, load, ice thickness and elastic pavement thickness The analysis of the influencing factors shows that in areas with low temperature and thick ice in the winter, if super-elastic pavement is used, self-breaking ice under BZZ-100 standard load can be realized; in winter, the temperature is slightly higher and the ice layer is thinner, Realize the car since breaking ice. At the same time, it is verified through laboratory tests that the low modulus elastic pavement is better than asphalt base pavement and self-broken ice, which is feasible.
