研究了粘土作为第三组分对聚合物改性沥青性能的影响。在对二元沥青/粘土和聚合物/粘土共混物进行初步研究之后，通过将粘土和聚合物单独地或以预混母料的形式添加到沥青中来制备三元共混物。插层纳米复合材料具有可比的层间距离和玻璃化转变温度，在这两种情况下获得。然而，结果表明，混合程序显着影响最终的流变性能。在线性粘弹性范围内建立的主曲线，并在频率和温度域中表示，有助于可视化和评估这种差异。(C)2008爱思唯尔有限公司保留所有权利。
The effect of the addition of clay as a third component in polymer modified asphalts has been investigated. After a preliminary investigation on the binary asphalt/clay and polymer/clay blends, the tertiary blends were prepared by adding the clay and polymer to the asphalt, either separately or in the form of a premixed master batch. Intercalated nanocomposites with comparable interlayer distances and glass transition temperatures were obtained in both cases. However, the results show that the mixing procedure significantly affected the final rheological properties. The master curves built in the linear viscoelastic range and represented in both the frequency and the temperature domains help to visualize and evaluate such differences. (C) 2008 Elsevier Ltd.
