| 摘 要： | 石油沥青中含有大量酸性及碱性化合物，为了研究沥青中官能团不同的组分对沥青性质的影响，利用离子交换色谱(IEC)将沥青按官能团分离成酸碱性不同的组分，并将IEC分离出的各个组分再以不同的比例回添到母体沥青中，考察沥青中各个组分对沥青粘度的影响，结果表明：中性组分和酸性组分增多时沥青粘度增大，碱性组分和两性组分增多时沥青粘度减小。

| Abstract: | Since many kinds of acid and base compositions exist in asphalt, IEC (Ion Exchange Chromatograph) was used as a kind of asphalt separating technology which can separate asphalt into different acid and base composition to study the influence of different composition on asphalt properties. The viscosity was determined after putting the compositions from IEC back into the base asphalt in different ratio. The results show that the asphalt viscosity increased with more neutral and acid composition but decrease with more base and amphoteric compositions. |
