摘要
综述了近年来废弃聚乙烯(WPE)改性基质沥青研究进展及应用现状.WPE是全球废弃塑料占比最大的固废材料,其在沥青中的研究及其应用具有重要意义.目前,相关研究大都集中在WPE改性沥青性能及其对性能变化进行微观表征、分析验证.有关研究结果表明,WPE改性沥青储存高温稳定性差及低温性能存在一定争议,据此,近年来研究人员积极开展WPE与其他聚合复合改性或对WPE进行高温裂化等技术制备改性剂并对改性沥青性能进行分析评价,取得了一定成果,但仍存在制约其推广应用的技术或成本局限.本文最后总体分析了国内目前WPE在改性沥青中应用技术现状,并进一步探讨分析预测了WPE改性沥青今后研究和应用前景.
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.
