针对陕西省各区域气候特征以及交通特性,研究相应区域的路面典型结构,提出路面典型结构设计方法,对于提高高速公路沥青混凝土路面长期使用性能具有指导意义。基于陕西省气象数据资料、实测轴载数据资料、路基强度数据资料,进行气候区域划分、交通等级划分以及路基强度等级划分,最终推荐出合理的路面典型结构。
In view of the climatic characteristics and traffic characteristics of various regions in Shaanxi Province, the typical structure of the pavement in the corresponding area is studied and the typical structure design method of the pavement is proposed. This method is of guiding significance to improve the long-term performance of expressway asphalt concrete pavement. Based on the meteorological data of Shaanxi Province, the measured data of axle load and the data of subgrade strength, the division of climate, the division of traffic grade and the classification of subgrade strength were conducted. Finally, a reasonable pavement typical structure was recommended.
