摘要
为比较不同沥青路面结构的野外长期使用性能,对日照—兰考高速公路菏泽—关庄段铺筑的3种山东省广泛使用的沥青路面结构进行跟踪观测,通过路面损坏状况、平整度、车辙深度、路面结构强度等指标的纵横向比较,得出沥青大碎石柔性基层+3cm抗疲劳层的路面结构使用性能最优,从而为公路建设及大中修养护提供数据支撑。
In order to compare the field long-term performance of different asphalt pavement structures,three kinds of asphalt pavement structures widely used in Shandong Province,paved in the Heze-Guanzhuang section of the Rizhao-Lankao Expressway,were tracked and observed.Through the vertical and horizontal comparison of several indexes such as road damage conditions,flatness,rut depth and structural strength,the study shows that the asphalt pavement of flexible base layer+3cm anti-fatigue layer has the best performance,which provides data support for highway construction and large and medium-sized maintenance.
