摘　　要：沥青混合料施工中,体积指标概念明确、试验操作简便易行,因而被广泛应用于实际工程质量控制中,在沥青混合料设计时首先需要满足空隙率体积指标,然后才进行其他性能检验。而空隙率体积指标与矿料级配联系密切,通过贝雷法设计矿料级配,通过试验分析了空隙率指标受矿料级配影响的变化规律。During bituminous mixture construction, the concept of volume index is clear and the test operation is simple and convenient, so bituminous mixture is widely used in praetical engineering quality control. The bituminous mixture is designed firstly to meet void ratio volume index, then other performance examination can be carried out. The void ratio volume index has a close relationship with mineral aggregate gradation which is designed by Berret Method. The change rule of void ratio under the influence of mineral aggregate gradation is analyzed by test.
