Abstract: Asphalt mixture bulk density is an important indictor, which has great effect on compact density and mixture design of asphalt pavement. Based on density definition of asphalt mixture, The paper shows deeply different measuring density methods effect on mixture design and quality control of asphalt pavement.The results show that the application of wax-enveloped method to measure bulk density of asphalt mixture is a fit and reliable, but is needs to pay attention to the detailed requirement of wax-enveloped.

Key words: asphalt mixture, bulk density, measure method, wax- enveloped method

摘要： 沥青混合料的毛体积实测密度是沥青路面中至关重要的一个指标,它不仅控制着沥青混合料配合比设 计,而且对沥青路面的压实度有着较大影响.笔者从沥青混合料密度的定义出发,深刻揭示了不同测定方法对 沥青混合料配合比和质量控制的影响,实验结果表明,沥青混合料的毛体积实测密度,采用蜡封法比较科学,但 应注意蜡封法的具体要求.
