| 摘 要： | 察哈尔地区有着丰富的玄武岩储存量,但缺乏对当地玄武岩集料和沥青混合料路用性能的研究。文章利用灰色关联度分析了玄武岩集料特性指标对沥青混合料路用性能的影响程度,提出了3种集料宏观指标用于察哈尔地区玄武岩选材的指导,并通过当地试验段的铺筑对关联度及路用性能的预估进行验证,证明灰色关联度分析法可以在一定程度上通过集料特性对混合料路用性能进行预测。

| Abstract: | Chahar region has abundant storage of basalt,but the studies of the properties of basalt aggregates and asphalt mixture for road performance are rare.In this paper,the influence of properties of basalt aggregates on that of asphalt mixture is studied with gray relational analysis.Three macro indicators are proposed to guide the selection of basalt in Chahar region.The method is demonstrated with a test section locally,showing that grey relational analysis is able to predict the pavement properties of asphalt mixture to some extent. |
