中文摘要：
通过对不同掺量的TLA改性沥青进行动态蠕变实验,并基于Burgers模型的粘弹理论进行拟合分析,重点分析了模型参数随温度和掺量的变化规律以及不同掺量的蠕变曲线的形状变化规律。结果表明,基于Burgers模型拟合TLA改性沥青蠕变曲线相关性较高;任一掺量的TLA改性沥青,随着温度的升高,所有的参数值均明显变小;GV值随温度升高降低,当掺量〉30%后,GV增大的幅度才较为显著;TLA改性沥青蠕变曲线3个阶段的形状与参数大小密切相关。
英文摘要：
Through the dynamic creep test of the TLA modified asphalt with different contents, based on the Burgers model viscoelastic theory fitting analysis, this paper focuses on the model parameter variation with temperature and content, and with different contents of the creep curve the shape variation. The results show that the higher of the TLA modified asphalt creep curve, any content TLA modified asphalt can be fifed by the Burgers model, as the temperature rises, all the parameter values were significantly smaller; the Gv values ri- ses by the temperature, the Gv rate of increase was more significant when the dosage is greater than 30%; the TLA modified asphalt creep curve shape of the three stages was closely related to the parameter size.
