【摘要】 部分信息已知,部分信息未知的系统称为灰色系统,笔者采用灰色关联熵分析法,分析了再生沥青化学组成与其材料性能之间的关联关系。首先,运用灰色关联熵法对再生沥青的化学组成与其常规理化性能进行分析,研究了再生沥青化学组成对针入度、软化点、密度的影响,所得结果与经验公式所得结果一致,证明了在再生沥青化学组成对再生沥青材料性能的影响研究中引入灰色系统理论、运用灰熵分析方法的可靠性。更多还原

【Abstract】 The system whose a part of information has been known and others are unknown is named as grey system.In this paper,the relationship between chemical make-up and physical-chemical performance of regenerated asphalt is analyzed by means of grey relation entropy method.The affection of the chemical composition to penetration,softing point,and density is explored,which is in accordance with experience formula.It proves that the grey system and grey relation entropy are reponsible in the research of the affection of chemical make-up to materical performance of regenerated asphalt.更多还原
