摘　　要：长寿命路面结构设计对于提升道路基础设施的持久性和经济效益至关重要。本文综合分析了长寿命路面的设计指标、设计指标、路面结构类型以及路面结构设计方法。首先,概述了长寿命路面的设计理念,强调了结构设计、施工技术、经济性和环境可持续性的重要性。其次,探讨了设计指标,需综合考虑路基路面的结构设计、排水系统和力学性能等多个方面。接着,描述了国内外常见的长寿命路面结构组合,并讨论了它们的设计考虑和适用性。此外,详细列出了沥青路面结构设计方法。最后,对当前的研究现状进行了总结,并对长寿命路面设计的未来趋势提出了见解。The design of long-life pavement structure is crucial to improve the durability and economic efficiency of road infrastructure. In this paper, the design index, design index, pavement structure type and pavement structure design method of Long-Life pavement are analyzed comprehensively. Firstly, the design concept of long-life pavement is summarized, and the importance of structural design, construction technology, economy and environmental sustainability is emphasized. Secondly, the design index is discussed, which should consider the structural design, drainage system and mechanical properties of roadbed and pavement. Then, the common combinations of long-life pavement structures at home and abroad are described, and their design considerations and applicability are discussed. In addition, the design method of asphalt pavement structure is listed in detail. Finally, the current research status is summarized, and the future trend of Long-Life pavement design is put forward.
