摘　　要：为研究OMMT/SBR复合改性沥青的性能,采用DSR、BBR测试方法,探究复合改性沥青在高温以及低温下的抗车辙、抗开裂性能。研究结果显示:复合改性剂的掺入对改性沥青的高低温性能进行了加强与改善,掺入有机蒙脱土旨在提高沥青高温性能是可行的。In order to study the performance of OMMT/SBR composite modified asphalt,DSR and BBR test methods were used to investigate the rutting and cracking resistance of the composite modified asphalt at high and low temperatures.The results show that the addition of compound modifier can strengthen and improve the high and low temperature properties of modified asphalt,and the addition of organic montmorillonite is feasible to improve the high temperature properties of asphalt.
