SMA集料的有效密度研究

Research on Available Density of SMA Aggregate

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 。

This article expatiates on the concept of the available density of aggregate along with the meaning of importing this concept. Combined with the practical working condition of the aggregate in the asphalt concrete, the method to determine the available density of aggregate are brought forward. Moreover, the method is tested by contrast experiment. And through contrast analysis with the test of surveying the greatest consistency of the asphalt concrete mixture (T0711-93), using the available density of the aggregate to calculate the greatest density of the concrete mixture is recommended.\;
