阿拉尔市交通参数分析与沥青路面结构设计

随着城市经济发展,阿拉尔市原有道路结构已不能适应交通量的增长需要,该市多条道路需要进行改建和翻修,交通轴载是路面结构设计的关键因素,通过对阿拉尔市各条主要道路进行交通量与轴载状况调查,分析交通量的组成、交通量增长率,对交通量轴载换算,同时结合本地区地质条件与道路病害情况,提出合理的沥青路面结构设计方案,并对路面结构厚度进行试算,为本市沥青路面结构设计提供参考。

Analysis of Alar Urban Roads Transport Data and the Design of Asphalt Pavement Structure

Along with the development of city economy in Alar,the original structure of roads already haven＇t adapt to the growth volume of traffic in Alar,there are several roads need to be reset and overhauled,the key factor of the road structure design is the axle loads of the transportation.In this paper,according to the inquisition of the volume of traffic and axle loads in these main roads,analyze the constitute and growth rate of the volume of traffic,carry on converting the volume of traffic to equivalent single axle loads.In the meantime combine the geology condition and the disaster of the road in Alar,put forward a reasonable structural design of the road,and carry on calculating the thickness of the road structure,then provide a reference to the design of asphalt pavement structure in Alar.
