国内外沥青混合料级配设计研究综述

Summary on Foreign and Domestic Research of Asphalt Mixture Gradation Design

我国沥青路面广泛出现的早期破坏和疲劳损坏,究其原因在于其混合料的级配设计是一个重要影响因素。此外,随着众多新型沥青材料包括一些结合料的应用,级配的选取成为材料发挥功能的关键环节。此次研究针对国内外最常见和最新的几种沥青混合料级配设计方法进行了分析,阐述了各种级配设计法的原理、关键环节和指标,为国内规范的改进更新和施工提供更为合理的设计理论作参考,也为新型改性沥青材料的应用提供级配选取依据。

Design of gradations is one of the most important procedure which might influence damaging condition of asphalt pavement,which also is the key point to exerting the good performance of newly developed modified asphalt materials.In this paper,a summary on foreign and domestic research of common asphalt mixture gradation or new design and their theories,key points and indexes are lay out to give some reference and gist for a more suitable guideline,field construction and gradation selection for new asphalt materials.
