应用灰关联熵分析法考察再生沥青的感温性能

APPLICATION OF GREY CORRELATION ENTROPY METHOD TO STUDY TEMPERATURE AFFECTION PERFORMANCE OF REGENERATED ASPHALT

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感温性能之间的关联关系。这种方法克服了灰色关联分析中的不足,对如何改善沥青感温性能提供了理论指导,避免了盲目性,并通过对再生剂进行富芳处理,验证了上述结论。

The system, whose parts of information have been known and parts have been unknown, was called as grey system. The paper analyses the relation degree of the regenerated asphalt chemical makeups to their temperature affection performance by means of the grey relation entropy method. The method overcomes the shortcomings in grey relation analysis and provides a theoretic direction for how to improve the temperature affection performance of asphalt, and avoids blindness. The conclusions are verified by means of abounding the aromatics of regenerating reagent.
