主要研究了沥青混合料空隙率试验中的有关问题 ,包括实测密度的测量、理论密度的计算以及空隙率计算等 .通过大量的室内试验得出了一些有益的结论 ,譬如理论密度计算的问题 ,和几种实测密度之间的关系等 ,为进一步标准沥青混合料空隙率的计算方法奠定基础 In this paper, we mainly study the related issues in the void fraction test of asphalt mixture, including the measurement of the measured density, the calculation of the theoretical density and the calculation of the void fraction etc. Some useful conclusions are obtained through a large number of laboratory tests, such as the theoretical density calculation, And the relationship between several measured density, etc., to lay the foundation for further standard method of calculating the porosity of asphalt mixture
