刚性基层长寿命路面结构设计与施工技术研究

Design and Research on Construction Technology of Long-life Pavement with Rigid Base

我国高速公路沥青路面的早期破坏严重,设计寿命严重不足,而长寿命路面以其优越的性能将被广泛应用。分析了国内外长寿命路面的研究现状,阐述了长寿命路面的定义和设计要求,结合工程实例从长寿命路面结构组合、材料选择和施工工艺等方面进行了探讨,对我国长寿命高速公路的建设与发展具有重要意义。

In China,early asphalt pavement has been damaged seriously and has serious shortage of design life.Long-life pavement with its superior performance will be widely used.First it analyzes the research status of long-life pavement at home and abroad,then describes the definition and design requirements of long-life pavement,finally discusses the engineering example from the combination of long-life,pavement structure,material selection and construction technology.It will play a grate role in construction and development of Chinese long-life highway.
