| 摘 要： | 通过SBS改性沥青混合料的单轴拉伸试验,分析了粘弹性模型与损伤模型的特性,并耦合成粘弹性连续损伤模型;从能量的角度考虑了SBS改性沥青混合料的疲劳损伤特性和损伤效应,并建立了一种与拉伸应变水平相关的疲劳损伤模型。模型与试验吻合较好,可预测不同拉伸应变水平下SBS改性沥青混合料的疲劳寿命。

| Abstract: | The characteristic of the visco-elastic models and the damage models have been analyzed by the SBS modified asphalt mixture monaxial tension tests,and coupling becomes visco-elastic and damage models in succession.The fatigue damage characteristics of the SBS modified asphalt mixture and damage effect in terms of energy has also considered and a kind of fatigue damage models correlated with tensile strain level,the models and testing identically better have been built,which can predict the fatigue life of the SBS modified asphalt(mixture) under different tensile strain competence. |
