Abstract

Abstract: Through the analysis of the principle and characteristics of Superpave mixture proportion design method and combining with the special aircraft load conditions, epoxy asphalt mixture proportion design of airport pavement was studied. The results show that design rotating compaction times are recommended to be 80 times by considering the particularity of the plane load. VA and VMA of design compaction times are selected as volume design indexes of epoxy asphalt mixture. The compaction degree of the initial rotation compaction times and the maximum rotating compaction times are selected as verification indexes of the optimal epoxy asphalt dosage. Finally, two aggregates were selected to carry out mixture proportion design and the optimal gradation was determined by comparison analysis. The optimum asphalt-aggregate proportion was determined to be 5.12%.

Key words: highway engineering, airport pavement, epoxy asphalt mixture, mixture proportion design, design rotating compaction

摘要： 通过对Superpave配合比设计方法原理及特点分析，结合机场特殊荷载条件，展开对机场道面环氧沥青混合料配合比设计的研究。结果表明：考虑到飞机荷载的特殊性，推荐选用设计旋转压实次数为80次，设计压实次数下的空隙率和矿料间隙率为确定环氧沥青用量的体积设计指标，并以初始旋转压实次数的压实度和最大旋转压实次数下的压实度作为最佳环氧沥青用量的验证指标。最后通过选择两种集料进行配合比设计，通过对比分析选择最优级配，并确定最佳沥青用量为5.12%。
