摘要
为研究超高温重载条件下机场跑道沥青道面的抗车辙性能,通过室内超高温车辙试验,分析车辙深度在不同温度、荷载和层间接触条件下的变化情况以及沥青面层类型、厚度和结构形式对道面高温抗车辙性能的影响。结果表明:增加黏油层或采用改性沥青材料能够显著提高沥青道面在重载条件下的高温稳定性;路面结构形式对沥青面层的高温稳定性有一定影响,其中动稳定度与相对变形指标并不完全一致。
In order to study the anti-rutting performance of asphalt pavement of airport runway under ultra-high temperature and heavy load conditions,the variation of rut depth under different temperature,load and interlayer contact conditions and the influence of type of asphalt surface layer,thickness and structural form on the anti-rutting performance of the pavement at high temperatures were analyzed by indoor ultra-high temperature rutting test.The results show that the high temperature stability of asphalt pavement under heavy load can be significantly improved by adding viscous oil layer or using modified asphalt material;the pavement structure has certain influence on the high temperature stability of asphalt pavement,and the dynamic stability and relative deformation index are not completely consistent.
