摘要:
废旧苯乙烯-丁二烯-苯乙烯嵌段共聚物（SBS）改性沥青混合料的大量堆积会造成严重的环境污染和资源浪费。本研究采用聚氨酯（PU）预聚体与1,4-丁二醇二缩水甘油醚（BUDGE）作为反应性有机物，利用Sasobit温拌剂，对老化SBS改性沥青进行温拌反应再生。通过动态剪切流变仪进行频率扫描和温度扫描试验，研究温拌反应再生对老化SBS改性沥青流变性能的影响，评价其再生效果。结果表明:Sasobit会使反应再生SBS改性沥青弹性成分增加，黏性成分减少，且Sasobit掺量的增加可以改善反应再生SBS改性沥青的抗变形能力，而抗疲劳开裂性能则反之；当温拌反应再生SBS改性沥青的车辙因子（G*/sinδ）为1 kPa时，对应的临界温度均为85 ℃，高温性能等级（PG）为PG82，说明温拌反应再生SBS改性沥青能保持较高的高温抗变形能力。
Abstract:
The disposal of large quantities of waste styrene-butadiene-styrene block copolymer （SBS）-modified asphalt mixtures leads to serious environmental pollution and resource wastage. In this study，a polyurethane（PU） prepolymer and 1,4-butanediol diglycidyl ether（BUDGE）were used as reactive rejuvenators，combined with Sasobit warm-mix additive，to rejuvenate aged SBS-modified asphalt through a warm-mix reaction process. Frequency sweep and temperature sweep tests were conducted using a dynamic shear rheometer to investigate the effect of warm-mix reaction-rejuvenation on the rheological properties of the aged SBS-modified asphalt and to evaluate the rejuvenation effectiveness. The results showed that the Sasobit increases the elastic component and reduces the viscous component of rejuvenated SBS-modified asphalt. An increase in Sasobit content improved the deformation resistance of the rejuvenated asphalt, but reduced its resistance to fatigue cracking. When the rutting factor（G*/sinδ） of the warm-mix reaction-rejuvenated SBS-modified asphalt reached 1 kPa，the corresponding critical temperature was 85 ℃，and the high-temperature performance grade（PG） was PG82，indicating that the warm-mix reaction-rejuvenated SBS-modified asphalt retains high deformation resistance at elevated temperatures.
