摘要
采用针入度评价体系和SHRP沥青胶结料PG分级体系研究掺加RET(0%～2. 0%)对TB复合SBS改性沥青高低温性能和流变特性的影响;通过荧光显微镜分析了TB+SBS改性沥青、RET复配TB+SBS改性沥青的微观形貌特征;采用车辙试验、低温弯曲试验、APA试验和四点弯曲疲劳试验研究了RET与TB复配SBS改性沥青混合料的高低温性能和抗疲劳耐久性能。
The effect of RET(0%-2.0%)on the high-low temperature performance and rheological properties of TB composite SBS modified asphalt was investigated by using a penetration evaluation system and SHRP asphalt binder PG classification system.TB +SBS was analyzed by fluorescence .microscopy. The micromorphology of SBS modified asphalt and RET compounded TB +SBS modified asphalt reveals the modification mechanism of RET on TB +SBS modified asphalt.It adopts rutting test,low temperature bending test,APA test and four-point bending fatigue,the high and low temperature performance and fatigue durability of SBS modified asphalt mixtures with RET and.TB were studied.
