为了研究环氧沥青混合料的粘弹性能,采用动态流变试验,通过动态频率扫描获得不同温度下环氧沥青混合料随频率变化的关系,分析了环氧沥青混合料的粘弹性能.同时结合室温等效原理,获得了动态剪切复数模量主曲线,在跨越19个数量级的频率范围内分析比较了环氧沥青混合料的粘弹性能.结果表明:环氧沥青混合料具有与普通沥青混合料类似的粘弹性变化规律,也存在各自的粘弹性差异.
The viscous-elastic properties of epoxy asphalt mixtures was studied by dynamic rheology test. The connections between dynamic sheer complex modulus and frequency of epoxy asphalt mixture were got by dynamic frequency sweep at different temperature. The viscous-elastic properties of epoxy asphalt mixture were analyzed. Master curves of dynamic sheer complex modulus changing along with the frequency were got by using time-temperature equal principle. So viscous-elastic properties of epoxy asphalt mixture were also analyzed in overstepping 19 magnitudes of frequency section. Results indicate that viscous-elastic property of epoxy asphalt mixture is same to ordinary asphalt mixture, but they have otherness.
