摘要/Abstract

摘要： 比较了老化前后三种国产沥青的DSC谱图及GPC谱图，对老化前后样品的吸热峰进行了分析，并通过GPC谱图计算了老化前后不同分子量区间组成所占有的百分数，对三种沥青抗老化性能的优劣做了评价。

Abstract: In this paper,based,on the comparison between the DSC pictures and GPC pictures of three China-made asphalts be-fore and after ageing, the endothermic peak of the samples are analysed, in the same time,the perceentage of the spaceoccupied by the different molecular weight before and after ageing, with the help of GPC pictures, is calculated, and the appraisal of the ageing property of the three asphalts is also presented.

Key words: differential seanning calorimetry, gd permeation chromatography, heatageing
