摘要
用灰色关联分析法研究了沥青抗老化性能与沥青化学组成之间的关联程度,结果表明,影响再生沥青性质的主要因素是沥青中的芳烃和胶质的含量。通过添加芳香组分能改善沥青四组分之间的配伍性,从而可以改善再生沥青的抗老化性能。并通过对再生剂进行富芳处理,验证了上述结论。
The relation degree of the asphalt chemical composition to its aging resistance was studied by the grey system.The results showed that the compatibility between the asphalt four components and the aging resistance could be improved.The conclusions were verfied by means of abounding the aromatics of regenerating reagent.
