摘　　要：通过不同条件下的沥青路面全厚度车辙试验,就中面层沥青类型、静荷载、路面材料和结构组合设计以及温度等因素对沥青路面车辙的影响进行了研究。结果表明三层沥青路面结构中面层采用改性沥青可以使动稳定度提高50%以上,静荷载引起的车辙变形约占总变形的25%,骨料岩石类别和温度变化对沥青路面车辙影响显著。There were many factors that resulted in rutting of asphalt pavement,including asphalt type,static load levels,materials,structure combination and temperature and so on.Through lots of total thickness rutting tests under different conditions,in this paper,the ruttings caused by above factors were studied.Based on test results,it was found that: The dynamic stability would have a more than 50% increase if modified asphalt rather than natural asphalt was used in the middle asphalt layer of a three asphalt lay...
