武汉市高新大道综合改造路面结构方案设计

Design of Comprehensive Reconstruction Pavement Structure of Gaoxin Avenue in Wuhan

通过介绍高新大道现状路面技术状况,分析病害原因,根据检测数据推算设计参数,采用长寿命路面设计理念,对老路加铺、全部破除新建、部分破除新建3种路面改造方案进行技术经济比较,确定老路加铺连续配筋混凝土复合式沥青路面的总体设计方案,并在此基础上对现状道路局部病害处理和特殊路段路面结构进行深化设计。

With the introduction of the current pavement technology of Gaoxin Avenue,the causes of the disease are analyzed.The design parameter is estimated according to the monitoring data.Based on the design concept of long-life pavement,the technical and economic comparison is made among three pavement reconstruction schemes,namely overlay construction to repair old roads,reconstruction of fully demolished old roads and reconstruction of partially demolished old roads.Finally,the overall design scheme of continuous reinforced concrete composite asphalt pavement is determined.On this basis,the local disease treatment of the existing road and the pavement structure of special sections are further designed.
