摘　　要：主要对沥青及其胶泥在0～35℃内的力学温度响应进行探讨,测试沥青及胶泥体系的温度相转变过程,引入玻璃化转变温度作为低温性能的评价指标,横向对比了不同标号沥青、老化方式对沥青低温性能及疲劳性能的影响,以及不同粉胶比对沥青胶泥的中、低温性能影响;初步讨论了沥青玻璃化温度和其他评价指标的相关性。This report mainly researched the dynamic temperature responses of asphalt and mortars by dynamic shear method. Asphalt and mortars phase transformation were measured and glass transformation temperatures （Tg） were obtained as an evaluation index, and fatigue performances were compared among different type, different aged asphalts and different filler--bitumen ratios mortars. Finally, the relativity between the Tg temperature and other evaluation index were discussed.

关 键 词：玻璃化温度 沥青 低温性能
