| 为解决公路超薄层罩面病害和体积设计方法的不足，以胶粉和SBS改性沥青为原料制备高性能胶粉改性沥青，采用体积性能平衡设计方法，对胶粉改性沥青TOM-10混合料进行配合比设计，对胶粉改性沥青TOM-10混合料的路用性能进行分析，并与SBS改性沥青TOM-10混合料进行对比。结果表明：胶粉改性沥青的耐高、低温和耐老化性能均优于SBS改性沥青；采用体积性能平衡设计方法设计的胶粉改性沥青TOM-10混合料的动稳定度、残留稳定度、劈裂强度比和最大弯拉应变均远大于规范要求；胶粉改性沥青TOM-10混合料的高温稳定性能、抗水损害性能、低温抗裂性能和耐疲劳性能优于SBS改性沥青TOM-10混合料，胶粉的加入可以提升沥青混合料的耐久性能。 |

| In order to solve the defect of road ultra-thin covering and the deficiency of volume design method，high performance rubber powder modified asphalt was prepared with rubber powder and SBS modified asphalt，and the mixture design of rubber powder modified asphalt TOM-10 mixtures was carried out by adopting volume performance balancing design method.The pavement performance of rubber powder modified asphalt TOM-10 mixtures was analyzed，and that was compared with SBS modified asphalt TOM-10 mixtures.The results showed that rubber powder modified asphalt had better high temperature resistance，low temperature resistance and aging resistance than SBS modified asphalt.The dynamic stability，residual stability，splitting strength ratio and maximum blending tensile strain of rubber powder modified asphalt TOM-10 mixtures by volume performance balancing design method were much higher than the standard requirements.The pavement performance（high temperature stability，water damage resistance，low temperature crack resistance and fatigue resistance） of rubber powder modified asphalt TOM-10 mixtures was better than that of SBS modified asphalt TOM-10 mixtures.The addition of rubber powder could improve the durability of asphalt mixtures. |
