| 摘 要： | 首先从理论计算入手，根据粗、细集料的物理性质，通过控制路面最终空隙率、矿粉用量和粉胶比等指标找到SMA等嵌挤型混合料结构的粗细集料之间的相关关系，得到细集料用量的计算公式。最后分析了影响细集料用量的相关因素。

| Abstract: | According to the physical features of coarse and fine aggregates, the correlation relation of coarse and fine aggregates in SMA by controlling index of percent air voids in pavement,dosage of mineral filler and powder asphalt ratio are found in this paper, Then the formulas of dosage of fine aggregate by theoretical calculation are got. Last, the influence factors of dosage of fine aggregate are analyzed. |
