基于模糊层次分析的纳米改性沥青改性剂比选

Comparison of nanometer modified asphalt modifier on the fuzzy analytic hierarchy process

为了优选纳米改性沥青的改性剂,提高纳米改性沥青的改性效果,本文引入模糊决策理论和层次分析法,应用层次分析法确定各影响因素的权重、模糊决策理论确定各评价指标的隶属度,建立了纳米改性沥青改性剂的多层次模糊综合评测模型,对影响改性效果的改性剂进行多指标和多因素的对比分析,结合实例分析,优选出了纳米改性沥青的最优化改性剂与改性方案。

In order to optimize the modifier nanometer modified asphalt,improve the modification effect of nano modi.fied asphalt,this paper introduces the fuzzy decision analysis theory and AHP method and uses AHP to determine the weights of the influence factors,the fuzzy decision theory to determine the membership of evaluation index.The multilevel fuzzy comprehensive evaluation model of nano-modified asphalt modifier is established.Through the comparison and analysis of multi index and multi factors on the modifiers that affect the modification effect,the optimal modifier and modification scheme of nano-modified asphalt are selected along with the case analysis.
