基于灰关联理论的橡胶粉改性沥青热老化性能研究

Research on Thermal Ageing Performance of Rubber Powder Modified Asphalt Based on Grey Associative Theory

基于灰关联理论,分析橡胶沥青制备工艺对橡胶沥青老化性能的影响。为保证橡胶沥青老化性能研究的准确性,采用"孤立变量法",通过固定其他因素并变换单个因素进行试验,分析各种因素对橡胶沥青性能的影响。采用灰关联分析方法对多组数据进行关联度分析,研究各影响因素与橡胶沥青老化性能的关联度大小,确定影响橡胶沥青老化性能的关键因素。

This paper analyzes influences of preparation technology of rubber asphalt on ageing performance of rubber asphalt based on grey associative theory.In order to guarantee accuracy of research on ageing performance of rubber asphalt,the paper adopts the isolated variable method to test by fixing other factors and transforming single factor and analyze influences of various factors on performance of rubber asphalt.The paper employs grey associative analysis method to analyze degrees of association of multiple groups of data,to study degrees of association of all influence factors with ageing performance of rubber asphalt,and to determine key factors that affect ageing performance of rubber asphalt.
