摘　　要：通过对相同型号,但原材料及配方不同的两种SBS改性沥青防水卷材在3种老化方式下性能变化的对比,对其耐久性进行了研究。结果表明:老化龄期相同时,自然老化对PE膜和沥青涂盖层的破坏比浸水老化和冻融循环老化更快、更严重;自然老化对卷材的厚度基本没有影响,而浸水老化和冻融循环老化会使厚度产生永久性增加;浸水老化对胎基的破坏作用高于自然老化和冻融循环老化。This article studies durability of two kinds of SBS modified asphalt waterproofing membrane with the same type but different raw materials and formula by comparison of performance changes in three aging modes. The results show that under the same aging age, the damage of PE film and asphalt coating during natural aging is faster and more serious than the aging of immersion and freeze-thawing cycle. Natural aging has little effect on the thickness of the membrane, and aging of immersion and freezing-thawing cycles causes a permanent increase in the thickness. The effect of immersion on the reinforcement is higher than that of natural aging and freezing-thawing cycle aging.
