本文以青岛海湾大桥项目为依托,对国际和国内常用的多种桥面沥青铺装层从破坏现象、损伤(坏)机理、材料设计、结构设计、性能评价及施工控制等方面进行综合分析,同时结合北方寒冷冰冻海域气候环境特点进行调研,从系统工程角度出发,按照铺装层层位功能定位的概念进行设计,对铺装层结构体系、防水体系以及混合料级配进行优化,以期建立适合我国北方沿海地区气候及交通荷载特性的铺装层混合料设计要求及技术标准体系。
Based on the project of Qingdao Bay Bridge, the paper analyzes the common failure modes of asphalt pavement widely used in China and abroad from the aspects of destruction, damage (bad) mechanism, material design, structural design, performance evaluation and construction control, In the meantime, according to the characteristics of the climatic environment in the cold and frozen waters in the north of the country, the system is designed according to the concept of functional positioning of the pavement layers. The structural, waterproofing and mixing gradation of the pavement layers are optimized to establish The design requirements and technical standards for the pavement mixture suitable for the climatic and traffic load characteristics in the northern coastal areas in China.
