【摘要】 长寿命沥青路面是在当前国际上受到普遍重视的一种全新的路面设计理念,通过分析世界各国长寿命路面研究成果,从长寿命路面设计理念、路面结构组合、路面设计方法、施工工艺、路用性能维护及经济分析等方面进行了探讨,揭示了长寿命路面具有区别于传统路面的结构特性,及具有优良的路用性能。建议修建高等级公路时能借鉴国外长寿命路面实践经验,提出基于长寿命路面设计理念的设计方法和施工工艺,以提高我国高等级公路的经济效益和社会效益。更多还原

【Abstract】 Perpetual pavement is currently being highlighted worldwide as a new concept of pavement design.Through the analysis of perpetual pavement research in various countries,some aspects of perpetual pavement are discussed,such as the concept of perpetual pavement,pavement structure combination,pavement design methods,pavement construction technology,performance maintenance and economic analysis.Then the structure characteristics of perpetual pavement are posted to be distinguished from that of traditional pavement structures,and to have good performance.Thus it is proposed to borrow ideas of perpetual pavement from foreign experiences in high-grade highway construction,and to put forward a design method and construction technology based on perpetual pavement design concept,which could enhance the economic efficiency and the social benefit of high-grade highway in China.更多还原
