影响沥青混凝土水稳定性的灰关联熵分析

Grey relation entropy method to analyze moisture stability of asphalt concrete

影响沥青混合料水稳定性的因素有沥青、矿料的性质、混合料的配合比、施工条件、环境因素等。为了分析这些影响因素显著性,采用改进的灰关联熵分析法,分析了影响沥青混凝土水稳定性的因素。结果表明:这种方法克服了一般灰关联度分析方法的不足,灰熵关联度大小不受分辨系数的影响;影响沥青混合料的水稳定性的主要因素为沥青的酸值和沥青的粘度,以及石料的碱值和石料的比表面积。

Some factors, included asphalt,aggregate,asphalt mixture performance,construction condition and environment, have effect on moisture stability of asphalt mixture.The grey relation entropy method was utilized to analyze the influence factors of moisture stability of asphalt concrete.The results indicated that the grey relation entropy method can overcome the disadvantage of normal grey relation method, the relation degree of grey entropy did not be influenced by discriminant factor. The main factors influencing moisture stability of asphalt mixture are acid value and viscosity of asphalt,alkali value and specific surface of aggregate.
