| 摘 要： | 为研究沥青混合料的时间-应力-温度依赖性,对3种沥青混合料进行了不同温度和应力水平下的静载蠕变试验,分析了温度、应力水平对沥青混合料蠕变特性的影响.结果表明:应力水平与温度对沥青混合料特征时间的影响相似,具有等效性;可以应用非线性黏弹性体的时间-应力-温度等效原理,推导出恒力温度位移因子、恒温应力位移因子和温度-应力联合位移因子;将沥青混合料在其他温度、应力水平下的蠕变曲线移位,可得到参考温度、参考应力水平下的蠕变主曲线.该研究成果也可为其他黏弹性材料的蠕变研究提供参考.

| Abstract: | Firstly,static creep tests of three asphalt mixtures were conducted at different temperatures and stresses respectively.And then the effects of temperature and stress on creep characteristic were studied. It is indicated that the influence of stress on the creep characteristic is similar to that of temperature for asphalt mixture,and the stress can be considered to exert the same effect on the viscosity as temperature. Finally,the time-stress-temperature equivalence principle of nonlinear viscoelastic mater... |
