摘　　要：沥青混凝土有优越的防渗性能与应变性能,越来越被广泛用于堆石坝心墙防渗结构材料。本文结合敦化抽水蓄能电站工程,对沥青混凝土心墙进行了摊铺试验,分析了碾压遍数与密度、孔隙率的关系,碾压温度与密度、孔隙率的关系。通过沥青混凝土物理力学性能检测,确定了沥青混凝土心墙现场施工参数和施工方法,为实际沥青混凝土施工和质量控制提供了依据。Asphalt concrete has excellent impermeability and strain performance and is more and more widely used as impermeable structural material for core wall of rockfill dam.In this paper,based on the project of Dunhua pumped storage power station,the paving test of asphalt concrete core wall is carried out,and the relationship between rolling pass number and density and porosity is analyzed,as well as the relationship between rolling temperature and density and porosity.Based on the test of physical and mechanical properties of asphalt concrete,the field construction parameters and construction methods of asphalt concrete core wall are determined,which provides a basis for the actual construction and quality control of asphalt concrete.
