摘　　要：通过系统的对比试验,研究了细集料类型对于沥青混凝土路面抗滑表层的抗滑性能以及沥青混合料的稳定性和耐久性的影响。作者建议选择棱角性好的碱性石屑作为路面表层混合料填隙细料,对于提高沥青混凝土的抗滑能力及其他路用性能具有重要的意义;当考虑到改善沥青混合料的施工和易性,或是由于料源限制必须使用天然砂时,应控制天然砂的含量,使其最好少于破碎石屑含量。On the basis of series of tests,the rules that different kinds of fine aggregate may have a remarkable affect on macrotexture of anti-skidding surface of asphalt pavement are indicated, and the stability and durability of asphalt mixture finally changed.Using fine alkaline aggregate in mixture to improve the anti-skidding performance and other performances of asphalt pavement are suggested. Thinking about the workability of construction or some other restrictions,it should be controled that the content of sand in mixture is less than cracked alkaline aggregate as fine aggregate in practice.
