胶粉/SBS复合改性沥青与SBS改性沥青、橡胶沥青的基本性能比较研究

摘要

Trough asphalt performance test and compound performance test modified asphalt, SBS modified asphalt, and rubber powder modified asphalt, for rubber powder/SBS compound differences in indicators such as softening point, low temperature ductility and needle penetration and in compound performance are analyzed comparatively. Allowing for comprehensive factors of indicator performance and cost control, rubber powder/SBS compound modified asphalt can have a wider application space.%通过对胶粉/SBS复合改性沥青、SBS改性沥青、胶粉改性沥青进行沥青性能试验和混合料性能试验,对比分析了三种沥青在软化点、低温延度、针入度等指标上的差异以及混合料性能上的差异。考虑指标性能和成本控制的综合因素,胶粉/SBS复合改性沥青可以有更广阔的应用空间。
