摘要
本文采用GPC(凝胶色谱)法测定了三种国产沥青的分子量、分子量分布、各个组分含量的百分数等,并以此与沥青的物理性能进行对应分析。结果表明:沥青的分子量与沥青的针入度、软化点、粘度有着密切关系。
The molecular weight, moleculdr weight distribution, content Percentage of each component of three kinds of domestic asphalt are analyzed by GPC in this paper, and the physial charactars of asphalt are analzzed correponding to above data. The result points out that the asphalt molecular weight is close relafed to asphalt penefration, softening point and viscosity.
