| 摘 要： | 京珠北高速公路途经多雾潮湿的粤北山区，路线纵坡大，长陡坡路段多，超载严重，沥青路面的抗滑性直接影响交通安全。就该段SMA混合料的配比设计及抗滑性能进行了系统研究，并深入探讨了SMA混合料矿料级配中4．75～2．36mm集料的用量及沥青用量对抗滑性的影响。

| Abstract: | Jingzhubei expressway passes by foggy and damp mountains in the north of Guangdong where there are large longitudinal grade of line, many long scarps and serious surcharge. So anti-slip performance of asphalt pavement influences traffic safety directly. In this paper, SMA mixture gradation design and anti-slip performance in this area were researched scientifically. Furthermore, the influence of aggregate content between 4. 75 mm and 2. 36 mm and asphalt content in SMA mineral aggregate gradation were studied deliberately. |
