摘要
对不同沥青品种、不同级配类型的十种沥青混合料进行了劈裂蠕变试验，分析了蠕变破坏过程中的能量损失规律。应用能量耗散理论分析蠕变累积能耗与应力水平关系，为用蠕变试验结果预测沥青混合料疲劳性能及建立损伤破坏统一模型奠定基础。
Ten types of bituminous mixtures, which are composed of different kinds of bitumen and grading, were tested with the splitting method for creep performance According to these experimental results, the regularity of dissipated energy in creep failure is analyzed Based on the energy dissipation theory, the relationship between creep cumulative energy and stress level is illustrated These provide a foundation for predicting fatigue property and establishing unifed model of damage and failure of bituminous mixture
