摘　　要：以某市政道路项目为依托,对比分析了三种不同改性沥青(SBS改性沥青、PE改性沥青、湖沥青改性沥青)混合料的高温抗车辙、低温抗开裂和抗水损害性能。研究结果表明,PE改性沥青的低温抗裂性和抗水损害性能最佳,高温稳定性仅次于湖沥青。综合各方面性能,PE改性沥青具有绝对的优势,更适合应用于本项目的路面铺筑,同时为本地区的其他市政道路路面建设提供一定的参考。Based on a municipal road project,the high temperature rutting resistance,low temperature crack resistance and water damage resistance of three kinds of different modified asphalt mixtures(SBS modified asphalt,PE modified asphalt and lake asphalt modified asphalt)are compared and analyzed.The research results show that,PE modified asphalt has the best low temperature crack resistance and water damage resistance,and its high temperature stability is second only to lake asphalt.Comprehensively considering the performance of all aspects,PE modified asphalt has absolute advantages,which is more suitable for the pavement construction of this project,and meanwhile it can provide a certain reference for the construction of other municipal road pavement in this region.
