摘　　要：环氧沥青是一种性能优异的改性沥青,主要应用于大跨度桥梁的桥面铺装,具有较为广阔的市场。目前,国内的环氧沥青主要依赖于进口,价格高昂,因此开发出国产环氧沥青是近些年的一个研究热点。由于环氧树脂和沥青的极性差异,如何解决相容性问题是环氧沥青研究的重点之一。本文主要综述了环氧沥青相分离的形成机理、相容性的研究方法以及增容的方法。Epoxy asphalt is a kind of modified asphalt with excellent performance,which has been mainly used in bridge deck paving of large-span bridges,and has a relatively broad market.At present,domestic epoxy asphalt mainly relies on imports and is very expensive,so developing domestically produced epoxy asphalt has been a research hotspot in recent years.Due to the polarity difference between epoxy resin and asphalt,solving compatibility issues is one of the focuses of epoxy asphalt research.In this article,the formation mechanism,compatibility research methods,and compatibilization methods of epoxy asphalt phase separation were mainly reviewed.
