摘　　要：应用双层OGFC路面结构,将纳米二氧化钛以拌合的方式添加到双层结构的上层。通过试验测试了双层OGFC路面的动稳定度、渗水系数、摩擦系数和构造深度,对比了添加纳米二氧化钛的双层OGFC和单层OGFC路面的降解尾气的效果。试验结果表明,双层OGFC路面具有较好的使用性能;减薄添加纳米二氧化钛的沥青层厚度,对尾气降解功能的影响不显著。添加纳米二氧化钛的双层OGFC路面具有排水、尾气吸收的功能,研究结果可用于降低城市交通引发的大气污染,铺筑环境友好型路面。This study presents a double-layer OGFC asphalt pavement structure, in which titanium dioxide was added in top layer in mixing way. Dynamic stability, permeability coefficient, friction coefficient and the texture depth were tested through pilot testing. The comparison of gas exhaustion efficiency of the double-layer OGFC and single-layer OGFC was conducted. Tests showed that the double-layer OGFC asphalt pavement had excel-lent road performance and reducing the thickness of asphalt containing nanometer titanium dioxide didn’t affect the exhaust decomposition. Double-layer OGFC asphalt pavement with nanometer titanium is good at water drainage and exhaust decomposition. The results can be used to reduce the air pollution caused by urban traffic and construct environmentally-friendly pavements.
