| 摘 要： | 利用分形理论这一研究工具对沥青混合料集料级配进行研究，建立沥青混合料集料级配分维数值与矿料间隙率的关系．对沥青玛蹄脂碎石混合料、多孔排水式沥青混合料、密级配沥青混合料进行试验研究，分别建立集料级配分维数值与矿料间隙率的关系，再分析、对比其他试验数据，得出矿料间隙率随着集料级配分维数值的增加先降低后增加、并在一定的范围内存在极小值的结论．此研究结论对沥青混合料设计级配的选择具有重要的指导意义．

| Abstract: | Based on the fractal theory,the gradations of asphalt mixtures are studied,and a relation is established between aggregate gradations' fractal dimensions and voids in mineral aggregate(VMA) in asphalt mixtures.A study is conducted on stone matrix asphalt(SMA),open graded friction courses(OGFC) and dense asphalt mixture(DAM),and the study result is compared with the results of former studies of other scholars.A conclusion is drawn that VMA in asphalt mixtures decreases at the very start and then continuously increases with the increase of aggregate gradations' fractal dimension and has a minimum value.This conclusion is instructive on the choice of aggregate gradations of asphalt mixtures. |
