摘　　要：为了改善景区道路的安全性和抗滑性,分析了级配的类型和集料的种类对沥青混合料各项性能的影响,特别是对沥青混合料的抗滑性能的影响。结果表明,采用中粒式沥青混合料适合于高温地区道路的高温稳定性要求;采用空隙率小于5%的密实混合料级配适合于湿润多雨气候条件下的沥青路面水稳性的要求。为了改善陡坡路段沥青路面抗滑性能,级配中应该增加粒径大于4.75 mm的粗集料的含量。In order to improve the safety and anti-skid property of the scenic roads, the affection of the types of gradation and aggregates on various properties of asphalt mixture has been investigated in this paper, especially on the anti-skid property. The results show that medium-size asphalt mixture is suitable for the high temperature stability in the high temperature region. The dense-graded mixture with less than 5% void content can satisfy the requirements for asphalt water-stability in the wet and rainy conditions. To improve anti-skid property in the steep slope, concentration of coarse aggregates with the diameter larger than 4.75 mm should be increased.
