论高速公路路面大修结构组合设计

Design for Structure Composition in Overhauling Expressway Pavement

以陕西省铜黄高速公路路面大修为例,通过对其路面结构组合设计思路的阐述,说明选择高等级公路沥青路面大修结构组合时,应建立在对原有沥青路面的现状和病害进行详细调查分析的基础上。针对道路现状、主要病害和养护大、中修工程的特点进行设计,提出科学、经济、合理的路面结构,对相关工程项目具有一定的参考价值。

Taking the pavement overhaul of Tongchuan-Huangling Expressway in Shaanxi Province as an example,by describing the design concept of pavement structure composition,it is illustrated that the choice of structure composition in overhauling expressway asphalt pavement should be based on the investigation of status and diseases of existing asphalt pavements.The design is conducted according to road status,major diseases and characteristics of overhaul,the scientific and economic pavement is put forward,which has a certain reference value for similar projects.
