水泥混凝土路面断面改造及加铺方案研究——以金巢大道为例

Research on Cross-section Reconstruction and Overlay Scheme of Cement Concrete Road for Jinchao Avenue

摘要:

以金巢大道提升改造工程为例，结合项目功能定位重新布设道路横断面，在详细评定老路状况基础上，提出沥青加铺方案，重点探讨了在道路断面重新布设时沥青加铺层的设计方案。分别就沥青加铺层材料选用、厚度选择，中间层的设置以及绑宽板块搭接做了分析，并提出具体做法，为以后类似项目提供借鉴。

Abstract:

Taking the Jinchao Avenue Upgrading and Reconstruction Project as an example and combined with the functional positioning of the project, the cross section of road is re-arranged. On the basis of evaluating the old road conditions in detail, the asphalt overlay scheme is proposed. The design scheme of the asphalt overlay is specially discussed when the cross section of road is re-arranged. The selection of asphalt overlay material, thickness selection, setting of intermediate layer and overlap of binding wide plate are analyzed respectively， and the specific methods are proposed, which provides the reference for similar projects in the future.
