摘　　要：为丰富筑路材料类型,降低工程费用,减少水土流失,分析了山皮土作为集料应用于高等级公路路基顶面补强层的可能性,针对山皮土颗粒不均匀、施工质量难以控制等问题,提出计算路基压实度的新方法,并用于检测施工质量。结果表明,采用新方法测定路基压实度符合山皮土特性,施工质量达到规范要求,且随着山皮土中山皮石含量的提高,材料强度增加,压实度提高,抗裂性能降低。In order to enrich road material types,reduce project expenses and water and soil loss,the possibility of hill-skill as aggregate applied for high-grade roadbed top surface＇s reinforcing layer is analyzed. Based on the uneven hill- skill particles,unmanageable construction quality,etc.,the new method of roadbed degree of compaction can be calculated,which is used to test the construction quality. The research indicates that the new methods used to test road bed degree of compactness conform to the properties of hill-skill soil and the construction quality is accordance with standard requirements. Besides,with the rising number of hill-skill stones content in the hill-skill soil,the material intensity increases,the degree of compactness increases and the anti-cracking ability decreases.
