废弃聚乙烯改性剂改性沥青研究及其应用技术进展
Research progress in application technology of waste polyethylene-modified asphalt
摘要
Abstract
This paper reviewed the research progress and application in waste polyethylene(WPE)-modified asphalt in re-cent years.WPE is a solid waste material with the largest proportion of waste plastics in the world,and its research and application in asphalt is of great significance.Most of relevant studies focused on the performance of WPE-modified as-phalt and its microscopic characterization,analysis,and verification of performance changes.These research results indi-cated that there were some controversies about the poor storage stability of WPE-modified asphalt in high-temperature and low-temperature performance.Therefore,researchers have actively performed the compounding modification of WPE with other polymers or the high temperature pyrolysis of WPE to prepare modifiers in recent years.They analyzed and evaluated the performance of modified asphalt and achieved certain results;however,there are still technical or cost limitations restricting its popularization and applications.Finally,the application technology of WPE-modified asphalt in China was analyzed,and its future research and application perspectives were discussed and predicted.关键词
