| 摘 要： | 为研究旋转压实次数对Superpave混合料设计及性能的影响,对Superpave20和Superpave25两种沥青混合料在不同旋转压实次数(75、100和125)下进行了设计,对得到的各类混合料进行了车辙、低温小梁弯曲、浸水马歇尔稳定度、冻融劈裂等试验,计算了沥青膜厚度,并铺筑了相应的试验段.通过室内试验和现场检测发现:增加旋转压实次数并不一定会降低设计沥青用量;当设计旋转压实次数增加25次时,沥青混合料动稳定度可以增加15%～30%;增加旋转压实次数对混合料的低温性能和抗水损害性能影响很小,沥青膜厚度随旋转压实次数的增加而增加.结果表明当集料的性能和现场施工工艺满足要求时,可适当的增加设计旋转压实次数,以提高混合料的路用性能.

| Abstract: | In order to study the effects of gyration compaction number on the design and performance of Superpave mixture,Superpave20 and Superpave25 asphalt mixtures were designed by using different gyration compaction numbers (75,100 and 125),and the various mixtures were evaluated by conducting wheel rutting,low-temperature bending beam,immersion Marshall stability and freeze-thaw split tests,asphalt film thicknesses were calculated,and corresponding field test sections were constructed. Test result shows that the ... |
