摘要
采用车辙试验、低温弯曲试验、冻融劈裂试验、应力控制模式下的间接拉伸疲劳试验,在分析RAP掺量(质量分数)对再生SBS沥青混合料各项性能影响的基础上,探究了高RAP掺量(60%)再生SBS沥青混合料的性能提升措施,此外,还通过旋转压实成型试验,研究了两种性能提升措施对再生SBS沥青混合料压实性能的影响。
Rutting test,low temperature bending test,freeze-thaw split test,and indirect tensile fatigue test in stress control mode are adopted to analyze the impact of RAP content（by mass） on the performance of reclaimed SBS asphalt mixture,in order to investigate the measures to improve the performance of reclaimed SBS asphalt mixture with high RAP content（60%）.Besides,gyratory compaction test is used to study the impact of these two measures on the compaction performance of reclaimed SBS asphalt mixture.
