摘要
研究了沈大、沈本等五种再生沥青的化学组成和结构,并与单家寺沥青进行了比较。由再生沥青的元素组成分析可知:再生沥青中碳氢含量在98%左右,其中C含量稍高,H含量稍低,氢碳原子比较小,氮的含量偏高;从再生沥青的平均分子结构参数(E-d-M法)可以看出:再生沥青的平均分子全部是多环结构,芳环稠合度较高,并且稠环系外周碳原子上侧链较少,平均分子中稠环烷烃比稠环芳香烃占优势。
The paper explores the chemical make - ups and structures of five kinds of regenerated asphalt. It can be seen from element analysis that the content of carbon and hydrogen carbon is high a little, the content of hydrogen and ratio of hydrogen is about ninety - eight percent, the content of and carbon are low a little, and the content of nitrogen is high excessively. By means of average molecule structure parameter（ E - d - M）, it can be seen that the average molecules are all joined - ring structure ,the density of aromatic rings is high comparatively, the side chain in the ring carbon atom besides density ring is less, and the density ring arene is dominated with alkane in the average mole structure.
