沥青贯入式碎石路面材料用量及施工工艺研究
Research on Material Consumption and Con-struction Technology of Asphalt Penetration Macadam Pavement

为进一步对沥青贯入式路面原材料用量进行研究，参考分级掺配的方法设计了沥青混合料的级配，利用体积填充的方法确定了沥青用量并通过试验说明了石料除尘及加热的必要性。通过足尺模型试验对原材料级配进行了验证，结果表明：通过分级掺配法使混合料骨料密实度增加，从而降低了石料和沥青用量。
In order to further study the raw material consumption of asphalt penetration pavement, the gradation of asphalt mixture was designed by referring to the method of gradation blending, the asphalt consumption was determined by volume filling method, and the necessity of dust removal and heating of stone material was explained through experiments. The gradation of raw materials is verified by full-scale model test. The results show that the gradation method can increase the density of aggregate and reduce the amount of stone and asphalt.
