阐述了集料有效密度的概念以及引入集料有效密度的意义 ,结合集料在沥青混凝土中的实际工作状态提出了测定集料有效密度的方法 ,并通过对比试验对该方法进行了验证 ,通过与测量沥青混合料最大密度试验(T0 711- 93)的对比分析 ,推荐采用集料的有效密度计算混合料的最大密度
The concept of aggregate effective density and the significance of introducing effective density of aggregate are introduced. Based on the actual working status of aggregate in asphalt concrete, a method of determining the effective density of aggregate is proposed. The method is verified by comparison test. Compared with the maximum density test of asphalt mixtures (T0 711-93), it is recommended to calculate the maximum density of the mixture by using the effective density of aggregate
