摘要
通过介绍桥面铺装使用要求和SMA的结构特点,对高弹体改性沥青和改性沥青SMA10进行了沥青及混合料性能对比试验,并在实体工程中应用。试验结果和实体工程使用情况说明,高弹体改性沥青SMA可以满足桥面铺装的要求,应用是成功的。
Through introducing the requirements of bridge deck pavement and structural characteristics of SMA, the asphalt performance and mixture performance are compared by tests for high-elastic modified asphalt and modified asphalt SMA10. The high-elastic modified asphalt SMA is used in practical projects. The results show that the high-elastic modified asphalt SMA can meet the requirements of bridge deck pavement.
