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.
In order to study the viscoelasticity of epoxy asphalt mixture, dynamic rheological tests were carried out to investigate the relationship between the epoxy asphalt mixture and the viscoelastic properties of the epoxy asphalt mixture at different temperatures by dynamic frequency scanning Combined with the principle of equivalent temperature at room temperature, the main curve of dynamic shear complex modulus was obtained, and the viscoelastic properties of epoxy asphalt mixture were analyzed and compared in the frequency range of 19 orders of magnitude.The results showed that: Asphalt mixture similar viscoelastic changes, but also their own viscoelastic differences.
