昆仑-欢喜岭SBS改性沥青的稳定性研究

Stability Research of Kunlun-Huanxiling SBS Modified Bitumen

昆仑-欢喜岭重交通道路沥青与SBS具有良好的配伍性,采用适当工艺,选择良好配伍的SBS改性剂,添加不同类型的稳定剂,使SBS与稳定剂发生化学反应,降低两种材料的界面能。对比基于现场改性不添加稳定剂的改性沥青,热储存稳定性及高温性能均明显改善,适于基地式生产并较长时间贮存,使用性能优异。

Kunlun-Huanxiling heavy road asphalt had good compatibility with SBS.Different stabilizers were selected to add to SBS modified bitumen by suitable processing,and with SBS had chemical reaction to decrease interface energy.By adding stabilizers,the thermal stability and high temperature performance of SBS modified bitumen were improved,and were available to in-situ production and long-term storage.
