摘　　要：面向中国长寿命公路建设工程的需求,介绍了中国、美国和欧洲各国长寿命沥青路面的基本概念和发展历程,总结了中国和欧美国家长寿命沥青路面设计理论与方法的研究和发展现状,梳理了欧美国家既有沥青路面检测与评价、延寿处治设计方法,论述了中国典型既有沥青路面延寿设计方法的研究与发展现状,对比分析了不同新建道路长寿命设计方法和既有沥青路面延寿设计方法的优缺点和适用性。研究结果表明:目前尚未形成统一的长寿命沥青路面设计标准,研究与应用仍处于发展完善阶段,长寿命沥青路面依旧是未来路面领域的研究热点;耦合交通与环境因素,建立多指标控制的长寿命沥青路面设计体系是今后应重点研究的方向;长寿命沥青路面结构设计在今后将向非线性、多维度、概率型和动态化转变;基于结构层寿命逐层递增的长寿命沥青路面延寿设计方法可使沥青路面结构使用年限翻一番,相关工作可为既有沥青路面延寿设计方法和体系的构建及应用提供有价值的参考和见解,以满足中国长寿命公路建设工程发展需求;既有沥青路面延寿设计是道路工程可持续发展的重要课题,未来应加强长寿命沥青路面技术的研究和推广,提高路面的综合质量,满足不断增长的道路运输需求,为建设优质、高效、绿色、安全的交通基础设施做出更大贡献。In the face of the demand for long-life expressway construction projects in China,the basic concepts and development histories of long-life asphalt pavements in China,the United States,and European countries were introduced.The research and development status of long-life asphalt pavement design theories and methods in China and European and American countries were summarized.The existing detection and evaluation for asphalt pavements and life extension treatment design methods in European and American countries were combed.The research and development status of life extension design methods for typical existing asphalt pavements in China were discussed.The advantages,disadvantages,and applicabilities of different long-life design methods for newly constructed roads and life extension design methods for existing asphalt pavements were compared and analyzed.Research results indicate that the unified design standard for long-life asphalt pavements is not formed at present.The research and application are still in the stage of development and improvement.Long-life asphalt pavements will still be a hot topic in the field of pavement research in the future.The coupling of traffic and environmental factors to establish a multi-index controlled long-life asphalt pavement design system should be a key research direction in the future.The long-life asphalt pavement structure design will shift towards nonlinear,multidimensional,probabilistic,and dynamic in the future.The life extension design method for long-life asphalt pavements based on the progressively increasing life of structural layers doubles the service life of asphalt pavement structures.The relevant work can provide valuable reference and insight for constructing and applying the life extension design methods and systems for existing asphalt pavements,so as to meet the development needs of long-life highway construction projects in China.The life extension design of existing asphalt pavements is an important subject for the sustainable development of road engin
