摘要
文章通过高温稳定性、动态模量及抗疲劳性能测试,分析了SMA改性沥青与聚氨酯复合材料在高速公路与城市道路裂缝修复中的适用性。研究结果表明,SMA改性沥青适合高温高负荷环境,聚氨酯复合材料则可以满足城市道路对柔韧性和抗老化性的需求,为沥青路面裂缝修复提供参考。
This article analyzes the applicability of SMA modified asphalt and polyurethane composite materials in crack repair of highways and urban roads through high-temperature stability,dynamic modulus,and fatigue resistance tests.The research results show that SMA modified asphalt is suitable for high temperature and high load environment,and polyurethane composite can meet the demand of urban roads for flexibility and aging resistance,providing a reference for asphalt pavement crack repair.
