摘要
采用动态模量试验、抗压强度试验以及劈裂试验在不同时间和温度条件下对三种沥青混合料力学特性的时温依赖性进行了分析,结果表明:在线弹性以及大变形条件下其均满足时温等效原理,并建立了不同力学参数的主曲线,以供参考。
The time-temperature dependency of mechanical parameters for three types of asphalt mixtures was evaluated using dynamic modulus test, compressive strength test and splitting test at different time and temperature conditions. It is found that they can satisfy the time-temperature superposition principle at linear elastic and large deformation conditions. Their master curves were also obtained, for reference.
