摘　　要：汽车尾气污染物的治理是交通运输"节能减排"工作的重要内容之一。纳米TiO2可降解汽车尾气,但如何使纳米TiO2与路面结合?通过对半柔性路面的结构特点与纳米TiO2光催化原理的研究,提出半柔性路面负载纳米TiO2的实用方法,通过玻璃微珠的间接负载以达到催化剂能够可持续利用的目的。同时解决了路面的抗滑,抗磨等性能。提高了纳米TiO2催化剂的耐久性能,通过半柔性路面的碱性水泥浆的中和反应,去除了催化剂表面附着的反应的终级产物无机酸,有利于催化剂的循环使用。可广泛应用于城市道路,高速公路道路与一些特殊路段中。为实践"资源节约,环境友好"和可持续发展的交通建设模式做出贡献,具有广阔的推广意义。It is one of the most important contents of the energy conservation and emission reduction in transportation to deal with the automobile exhaust pollutants. In this essay the practical method of nano-Ti02 immobilized on the semi-flexible pavement was put forward through the study of structural characteristics of the semi-flexible pavement and principles of the nanometer Ti02 photo-catalysis. Sustainable use of the catalyst can be achieved through indirect load of glass beads. The performance of antiskid and wear resistance can be also achieved. And the durability of nano-TiO2 catalysis will be improved too. The inorganic acid of the ultimate product of the reaction can be removed from the surface of catalysis after neutralization reaction of alkaline cement mud of the semi-flexible pavement. This is good for the recycling of catalysis. This technology can be widely used in urban roads, highways and some special pavements. Great contributions will be made in the traffic construction mode of resource saving, environmental friendly and sustainable development. Therefore, there is a wide oooularized sianificance.
