橡胶颗粒沥青混合料在冰雪地区道路的应用

Application of Granulated Rubber Asphalt Mixture in Roads of Snow Ice Area

冰雪地区的道路安全问题一直困扰道路交通部门,对路面抑制冰雪技术进行研究具有重要意义。橡胶沥青混合料是将橡胶沥青颗粒直接以骨料的形式掺入混合料代替部分集料形成新型的沥青混合料。橡胶颗粒的掺入能够帮助路面有效抑制积雪结冰,为冰雪地区的道路行车安全提供了解决方案。就橡胶沥青混合料路面和普通沥青路面的使用性能进行了观测和对比,发现橡胶颗粒的掺入能够提高沥青混合料路面的除冰性能、抗滑性能和抗变形能力,既有利于行车安全又能增强路面的耐久性。

The road security is always a difficult problem for the transportation administrators in the snow ice areas.It is very important to study the snow ice suppression technology of pavement Granulated rubber asphalt mixture is a new asphalt mixture of mixing the granulated rubber asphalt directly into the mixture in the form of aggregate to replace the partial aggregates.The mixed granulated rubber can be effectively to restrain the snow and ice on pavement and can provide the solving scheme for the driving security of roads in snow ice areas.This paper analyzes and compares the using performances of the rubber asphalt mixture pavement and the common asphalt pavement.The result shows that the mixed granulated rubber can improve the deicing performance,anti-sliding performance and anti-deformation capacity of asphalt mixture pavement,which is advantageous to the driving security as well as increases the durability of pavement.
