聚合物改性沥青机理研究(之一)——改性剂对轻质组分的吸收作用及体系的聚集态

The Study on the Mechanism of Polymer Modified Asphalt(Part 1) ——Absorbing-action of modifier to light constituent in asphalt and the state of aggregation

通过组分分析、溶度参数测定、DSC分析等项试验 ,证明 PE、SBS、EVA等改性剂能够吸收沥青中的饱和分、芳香分、蜡分等物质而溶胀 ,改变了自由沥青的组分比例和结构 ,使改性沥青这一多项体系的物理。

Through the analysis of asphalt consitiuent and the measurement of solubility parameter and the test of DSC, it is proved that the modifiers to asphalt such as PE, SBS and EVA can change the component ratio and the structure of original asphalt because of absorbing staurates, aromatics and paraf-finwax substances in asphalt, making the phisical and mechanical properties and the state of aggregation on the multiphase of modified asphalt change.
