Performance properties of polymer modified asphalt (PMA) binders with Styrene-isoprene-styrene (SIS), petroleum resin (PE), and ground tire rubber (GTR) were evaluated at high, intermediate, and low temperatures. Styrene-butadiene-styrene (SBS) PMA binder of PG 76-22 was used as a base binder. The PG76 SBS PMA binders were blended with SIS, PE, and three different GTR contents (0, 5, and 10%). The binders were artificially short-term and long-term aged using rolling thin film oven (RTFO) and pressure aging vessel (PAV) procedures. Superpave binder tests were conducted on the binders through rotational viscometer (RV), dynamic shear rheometer (DSR), and bending beam rheometer (BBR). Multiple stress creep recovery (MSCR) test was also performed to evaluate the rutting property. The results of this study indicated that (1) the addition of PE can decrease the binder viscosity, (2) although the incorporation of GTR and SIS significantly improve the rutting resistance of the binders, the effect of PE is found to be insignificant, (3) PE is observed to have positive effect on the cracking properties of control PG76 SBS PMA binder blended with SIS and GTR, and (4) incorporation of PE might be an useful option to improve the workability of high performance PMA binder in lieu with maintaining good rutting and cracking resistance.

SBS改性的含有GTR，SIS和PE的沥青粘合剂的实验室评估

在高温，中温和低温下评估了聚合物改性的沥青（PMA）粘合剂与苯乙烯-异戊二烯-苯乙烯（SIS），石油树脂（PE）和磨碎的轮胎橡胶（GTR）的性能。PG 76-22的苯乙烯-丁二烯-苯乙烯（SBS）PMA粘合剂用作基础粘合剂。将PG76 SBS PMA粘合剂与SIS，PE和三种不同的GTR含量（0％，5％和10％）混合。使用轧制薄膜烘箱（RTFO）和压力老化容器（PAV）程序对粘合剂进行了短期和长期的人工老化。通过旋转粘度计（RV），动态剪切流变仪（DSR）和弯曲梁流变仪（BBR）对粘合剂进行Superpave粘合剂测试。还进行了多次应力蠕变恢复（MSCR）测试以评估车辙性能。
