摘要
研究了不同添加剂对煤沥青筑路油改质的影响，利用ＩＲ光谱测定了改质前后沥青质官能团的变化情况，结合改质前后筑路油的族组成与性质的变化，提出了相应的改质机理。
The influence of different additives on pitch road binder modification was stud- ied. The change of functional-group modified of asphaltine was determined by IR differential spectra to investigate modified mechanism of additives. The modified mechanism was given by the changes of group-composition and property as welI as functional-group after additives.
