浅谈改性沥青

A brief discussion of modified pitch

简述了改性沥青的概念,高分子聚合物改性沥青的分类、特性、应用范围以及改性沥青的评价标准。未来沥青材料的主要研究方向是新型沥青改性剂和沥青改性产品的开发以及完善现有的沥青评价体系,同时,建立能够综合描述沥青各种性能的理论模型也是未来改性沥青研究的重要范畴。

Sketch the concept of the modified pitch,the classification,the characteristic and application range of the modified pitch of high polymer and the evaluation criteria of the modified pitch.The main research direction for the pitch material in the future lies in the new-type pitch modifier and development of pitch-modified produce and perfection of the existing pitch appraision system.Meanwhile set up the theorical model which can describe different performance of pitch synthetically.It is an important category that the modified pitch is stuided in future too.
