路面结构组合设计是路面设计的重要组成部分。以往路面设计方法对路面各层的作用和受力特点考虑不足,从而导致路面结构设计欠合理,致使路面损坏(尤其是重载交通)日益严重。依托广梧高速公路开展的重交通长寿命沥青混凝土路面设计施工技术研究课题,是在吸收国外已有长寿命路面结构研究经验的基础上,结合我国多年的研究实践积累,提出了考虑路面各层受力特点和作用的长寿命路面结构组合设计方法,并修建了3种试验路结构。
Pavement structure design is an important part of pavement design. In the past, the method of pavement design did not consider the function and stress characteristics of pavement. As a result, the pavement structure design was not reasonable, which caused the pavement damage (especially overloaded traffic) to be more and more serious. Relying on the Guang-Wu Expressway to carry out heavy-traffic long-life asphalt concrete pavement design and construction of technical research topic is based on the absorption of foreign experience in long-lived pavement structure, combined with many years of research and practice accumulation in our country, Stress characteristics and role of long-life pavement structure design method, and the construction of the three test road structure.
