摘　　要：沥青碎石基层作为柔性基层能够增强路面排水能力,缓解高速公路重载交通下的动水压力,并能减少沥青层的湿度收缩裂缝,防止反射裂缝的发生,从而改善路用性能,提高其使用寿命.结合徐州绕城西段高速公路沥青碎石基层施工,对沥青碎石基层的配比设计、施工控制要点及质量检验标准等重要环节进行了阐述分析.As the flexible basement layer,the asphalt macadam base course increases the surface drainability,alleviates the hydrodynamic pressure under heavy-duty transportation,decreases temperature contraction cracks in the bituminous mat and avoids reflection cracks,so as to improve the highway service performance and extend its service life.Based on the construction of asphalt macadam base course in Xuzhou west-ring expressway,this paper discusses the important links such as the mixture ratio design,main working control points and QCS（quality control standards）.
