基于力学响应敏感性的沥青路面设计指标分析

Analysis on Asphalt Pavement Design Index based on Sensitivity of Mechanical Response

以云罗高速公路无机结合料稳定类沥青路面试验路给定的结构型式为基础,分别针对2006版、2017版《公路沥青路面设计规范》和壳牌(SHELL)设计法中的设计指标,利用四因素三水平正交试验,得到极差以进行力学响应的敏感性分析。敏感性分析结果表明:2017版《公路沥青路面设计规范》克服了2006版设计规范中的弯沉难以协调各项单项指标及路面结构型式单一的缺点,2017版设计规范中的设计方法更具有开放性,设计者可选择空间更大。

Based on the structural patterns given by the asphalt pavement test road of the inorganic binder stabilized based in the Yunluo Expressway,respectively for 2006 edition and 2017 edition of the Specifications for Design of Highway Asphalt Pavement and SHELL design method in the design index,Using the four-factor three-level orthogonal test,the range for the sensitivity analysis of the mechanical response have been obtained.Sensitivity analysis results have shown that：2017 edition of the Specifications for Design of Highway Asphalt Pavement overcomes the shortcomings in 2006 edition of the design code,where the deflection being difficult to coordinate the individual indicators and the single pavement structure,2017 design specifications in the design method is more openness that provided larger choice space for designers.
