摘要： 通过对石灰岩、砂岩、玄武岩、花岗岩4种集料的磨光值试验、磨耗值试验、冲击值试验、压碎值试验、坚固性试验等试验进行了分析，并对几种集料的抗滑耐磨性能进行了研究。通过以上研究得出：在标准条件下所选用的几种集料的力学指标存在一定的相关性；本研究中使用的石灰岩、砂岩相当的石灰岩、砂岩作沥青路面抗滑表层的集料，在技术上是可行的；在交通量不大且地形平缓时，采用石灰岩作为抗滑表层的集料基本可以满足高速公路使用期内（大中修之前）的抗滑耐磨性能。通过以上各个方面的研究，从抗滑耐磨的角度综合分析、评价采用石灰岩、砂岩、玄武岩、花岗岩4种集料作为沥青抗滑表层材料的可行性。

Abstract: The polishing value test, wear value test, impact value test, crushing value test and soundness test on four kinds of aggregates, such as limestone, sandstone, basalt, and granite were analyzed. And the sliding and wearing resistances of the above aggregates were also studied. It is indicated that the mechanical indexes of the above aggregates at the standard test conditions are correlated at a certain degree. It is feasible in technology that using the proposed limestone and sandstone to be the aggregates of the anti-sliding layer of the asphalt road pavement. When the traffic volume is not large and the landform is even, using limestone as the aggregate of the anti-sliding layer can basically satisfy the requirements of slide and wear resistance of highway in operation (before the medium and large repair). Through the research on above aspects, the feasibility of using four kinds of aggregates, such as limestone, sandstone, basalt and granite as the material of asphalt anti-sliding surface was comprehensively analyzed and evaluated from the point view of slide and wear resistance.
