【摘要】 本文以甘肃省兰—白，馋—柳两条高速公路级配设计任务为依托，从SMA混合料的结构特点出发，对沥青玛蹄脂和矿料级配分别进行了研究。 通过变化纤维用量和矿粉用量研究了其对沥青玛蹄脂性质的影响，分析了矿料级配对体积指标的影响，并通过试验分析研究了其各自对混合料的低温和高温路用性能的影响，最后初步确定了适合甘肃省气候特点的SMA混合料级配。更多还原

【Abstract】 Relying on the research item of the LanBai and ChanLiu highway construction in Gansu province, the dissertation analyses the structural characteristics of SMA mixture and makes a detailed research on asphalt matrix and aggregate graduation. Firstly, the dissertation gives an elaborate discourse on inflence on asphalt matrix with variation of fiber and mineral filler content. Subsequently the inflence on volum index with the change of aggregate graduation is analysed. Moreover, by means of indoor and road test of SMA mixture, road performance of SMA is discussed. Finally, the applicable aggregate graduation of SMA mixture for the climate in Gansu province was recommended.更多还原
