用聚集态和分子量解释沥青的性能

The Influence of the Molecular Weight and the State Transition Characteristic on the Performance of Asphalt

采用物理力学试验方法及化学分析手段ＧＰＣ、ＤＳＣ等对沥青的性能进行了研究，在试验结果及分析的基础上，提出了采用聚集态和分子量的概念来解释不同沥青的高、低温性能及感温性的差异。

The GPC and DSC chemical means are adapted to study the performance of asphalt in this paper. Based on the test results and analysis, the paper presents, the concept of constituent state and molecular weight, with which to explain the performance of asphalt.
