集料有效密度测试方法研究

Study on Testing Effective Density of Aggregate

沥青混合料体积设计法成功的关键在于集料的密度参数能反映集料在沥青混合料中的实际情况 ,集料有效密度参数是最能反映实际情况的密度指标。通过分析集料有效密度的影响因素 ,对多种试验方案结果进行了比较 ,提出了简便、合理的有效密度测试方法。

A successful volume design of asphalt lies in the fact that the aggregate density parameters can reflect the actual condition of aggregate in the mixture, i.e. the effective density parameter. Through analysis of factors affecting the effective density of aggregate, comparisons are made of multiple testing proposals, which generate a simple and rational testing method.\;
