复合式基层长寿命沥青路面设计指标和设计标准研究

Research on Design Index and Design Standard of Perpetual Asphalt Pavement with Composite Base

通过分析高速公路半刚性基层路面结构,应用国外长寿命路面设计理念,提出复合式基层长寿命沥青路面结构的力学设计指标;通过借鉴国内外相关参数的研究成果,进行参数修正,提出了适合复合式基层长寿命沥青路面结构的设计标准。该研究成果对中国长寿命路面结构设计有一定的指导意义。

Through the analysis of semi-rigid base pavement structure for expressway and the application of design concept for perpetual pavement abroad, mechanical design indexes for the composite base perpetual asphalt pavement structure are proposed. Based on the research achievements of the related parameters at home and abroad, design standards for the perpetual asphalt pavement with composite base is proposed through parameters correction.This research achievement has certain guiding significance for design of the perpetual pavement structure in our country.
