Abstract: The snow melting and deicing coating technology has shown a good application value in preventing ice/snow from ice and snow in
the fields of Aeronautics and Astronauties,
n and electricity. With the development of the coating industry and the deep concept of
functional preventive maintenance, the technology of inhibiting/removing ice and snow coating has become a new research direction in the ice and snow technology, The research progress of pavement snow melting and deicing coating materials is introduced, and the superiority of coating method compared with other active pavement snow and ice removal technology is discussed. In this paper, the mechanism of snow melting and the performance evaluation of ice and snow are deseribed, and a new and simple device for simulating the ice breaking test is proposed.
Keywords: coating technology; bonding between ice and pavement; snow melting deicing
冬季或初春在我国北方及南方湿冷地区,路面结冰问题较为常见,严重影响着人民生产生活和道路通行运营。特别是在长大下坡、陡坡急弯等特殊路段,在抗滑性下降的冰雪路面上行驶汽车容易跑偏、打滑,极易造成车辆刹车失灵、侧翻等严重安全事故。
传统的路面除冰雪技术如表1(4]所述,其中撒布融雪剂、氧盐等被动式路面除冰方法都存在污染环境、腐蚀道路构筑物及沿线设施和降低沥青路面使用
