详细论证分析了由计算法、实测法确定的沥青混合料理论最大相对密度计算空隙率、矿料间隙率及沥青泡和度等体积指标结果的异同,并结合实例计算,比较了同类体积指标的大小;指出了计算分析矿料间隙率与沥青饱和度时应注意的问题;提出了确定理论最大相对密度应采取的方法。 In detail, the similarities and differences between the maximum relative density of asphalt mixture determined by the calculation method and the actual measurement method were calculated, and the volumetric indexes such as void fraction, mineral material void fraction and pitch blister were calculated and compared with the same volume index Size, pointed out the problems that should be paid attention to in calculating and analyzing the porosity and bitumen saturation, and proposed a method to determine the theoretical maximum relative density.
