摘要
论述了利用热缩聚方法对中温沥青进行改质处理来生产改质沥青 ,提高了沥青的软化点、β树脂含量及结焦值 ;并介绍了生产工艺的特点。
The production of modified asphalt by a modifying process of heat polycondensation from asphalt with medium softening point was introduced. The modified asphalt had a higher softening point, β-resin content and coking value. the characteristics of the process, main technological parameters and product quality were also introduced.
