Nampula-Cuamba道路升级改造工程路面结构设计

Design of Pavement Structure for Nampula-Cuamba Road Upgrading Project

结合莫桑比克Nampula-Cuamba道路升级改造项目,针对道路设计中路面结构的组成及厚度的确定进行阐述。通过分析计算结构层应力-应变,采用南非路面结构设计规范,对路面结构的疲劳寿命、车辙等设计指标进行了计算,从而最终确定路面结构设计。

Combined with the Nampula-Cuamba Road Upgrading Project in Mozambique, the determination of component and thickness of the pavement structure in the road design was elaborated. By calculating and analyzing the stress and strain in the structural layers, the design indices for pavement structure, such as fatigue life and rutting, were calculated according to the code for design of pavement structure in South Africa, thus the design of the pavement structure was determined finally.
