环氧沥青混凝土性能灰关联分析

Analysis on Properties of Oxygen-Asphalt Mixtures by Grey Relation Theory

通过对不同试验条件的控制,以马歇尔稳定度为基本评价指标,对环氧沥青混凝土性能影响因素进行灰关联分析。本次试验主要涉及的条件因素为环氧含量、油石比、空隙率、拌和保温温度、拌和保温时间。采用灰关联的分析方法,得到不同因素对环氧沥青混凝土的马歇尔稳定度的影响程度结果为环氧含量>油石比>拌和保温温度>拌和保温时间>空隙率,从而为环氧沥青混凝土的设计施工提供指导。

The oxygen-asphalt mixtures properties are analyzed by grey relation theory under different test conditions. It takes Marshall stability as the fundamental index of evaluation. The elements that the test mainly involves are oxygen contents, bit- umen aggregate ratio, percentage of void, the mixing heat preservation temperature, the mixing heat and preservation time. Adopting the analytical theory of the grey relation, the impact degree of different elements on Marshall stability of the oxygenasphalt mixtures is worked out, that is,oxygen contents 〉 bitumen aggregate ratio 〉 the mixing heat preservation temperature 〉 the mixing heat and preservation time 〉 percentage of void. Thus it can provide guide to the design and construction of the oxygen-asphalt mixtures.
