摘　　要：为了延长沥青路面结构的使用寿命,确保路面结构在寿命期内不发生结构性破坏并有效降低其在寿命期内的总费用,借鉴全寿命周期沥青路面设计理念并引入沥青路面极限寿命概念,针对依托工程重交通特点,对路面结构设计参数及设计指标进行研究,运用全新的优化模型对沥青路面厚度进行优化,结合工程实际情况,提出适合于重交通的全寿命周期沥青路面合理结构。结果表明,提出的路面结构既能满足寿命期内的力学性能要求和使用性能标准,还具有寿命期内经济性最优的特点,且能够满足重交通需要。Abstract： In order to prolong the life of asphalt pavement structure, ensure that the pavement structural failure did not occur during the life period and effectively reduced total cost during the lifetime, used for reference the Design Idea of the Total Life Cycle Asphalt Pavement and introduced the concept of asphalt pavement limit life, Based on heavy traffic characteristics of the the backing project, Studied on the pavement structure design parameters and design specifications, Used the new optimization model to optimize the thickness of asphalt pavement. Combined with the actual situation of the backing project, proposed the reasonable structure of the full-life cycle asphalt pavement suited for the heavy traffic. The results show that the proposed pavement structure can not only meet mechanical property requirements and the standard of using performance in the lifetime, but also has the optimal economic characteristic during the life period , maenwhile, can meet the heavy traffic characteristics.
