摘　　要：为研究不同沥青在新疆高温抗车辙地区的老化性能衰减规律,本文以新疆本地生产的50#沥青、70#沥青、SBS改性沥青为研究对象,进行了短期老化、长期老化、紫外老化模拟试验,利用沥青基本性质试验、傅里叶变换红外光谱试验、原子力显微镜试验对比分析了不同沥青在该地区的老化性能变化规律。结果表明:SBS改性沥青的官能团指数增长速率小于50#沥青、70#沥青;SBS改性沥青粗糙度参数变化幅度小于50#沥青、70#沥青;在高温抗车辙地区,SBS改性沥青老化衰减速率小于50#沥青、70#沥青,耐老化性能更优。The 50#asphalt,70#asphalt and SBS modified asphalt produced locally in Xinjiang were used to investigate the aging performance of different asphalts in high temperature anti-rutting area in Xinjiang.And short-term aging,long-term aging and UV aging simulation tests were carried out.In addition,the basic properties of asphalt,fourier transform infrared spectroscopy and atomic force microscopy tests were used to compare and analyze the aging properties of different asphalts in high temperature anti-rutting area in Xinjiang.The results show that the growth rate of the functional group index of SBS modified asphalt is less than that of 50#and 70#asphalts;the degree of change of roughness parameters of SBS modified asphalt is less than that of 50#and 70#asphalts;the decay rate of SBS modified asphalt is less than that of 50#and 70#asphalts in the high temperature anti-rutting area,and the aging resistance is better.
