摘要
高黏度改性沥青具有在60℃温度下黏度可高达20000 Pa·s的优势。其主要用作开级配排水沥青路面铺装层(open-graded friction course,OGFC)的胶结料黏结路面的大颗粒集料。结合近年国内外道路领域的研究成果,综述了高黏度改性沥青常用改性方法和路用性能,并对其主要优点以及当前存在的问题进行了分析,对高黏度改性沥青未来的发展趋势进行了展望。
High-viscosity modified asphalt has the advantage that its viscosity can reach up to 20,000 Pa•s at 60℃.It is mainly used as a binder in open-graded friction course(OGFC)pavements to bond large aggregate particles.Based on domestic and foreign research results in the road field in recent years,this paper summarizes the common modification methods and road performance of high-viscosity modified asphalt,and analyzes its main advantages and existing problems.Finally,the future development trend of high-viscosity modified asphalt is prospected.
