摘要
我国引进并应用SMA路面已有二十余年,因其良好的性能和工程实践效果,在我国高等级公路和市政道路中得到了大量应用。与欧美已经普及应用SMA路面相比,我国SMA路面应用呈现出两大特点:东部沿海地区应用规模和范围大,中西部地区起步晚,应用规模小;集中应用于高等级公路,市政道路应用少。进一步分析表明,成本和技术是造成我国尚未大规模、大范围普及SMA路面的根本原因。
The SMA pavement has been introduced and applied over 20 years in China, and has been widely used in high-grade highways and municipal roads because of its excellent performance and engineering practice in China. However, compared with the SMA pavements having been widely used in Europe and the United States, the application of SMA pavement in China presents two major characteristics that the application scale and scope are large in the eastern coastal areas, and small in the mid and west areas where the application of SMA pavement started late, and more application in high-grade highways and less application in municipal roads. The further analysis shows that the cost and technologies are the root cause to block the popularization in large scale and scope of SMA pavement in China.
