| 摘要: |
| 采用动态模量试验,研究了浇注式沥青混合料（GA10）流变性，分析了GA10动态模量和相位角对温度及荷载频率的依赖性，提出了表征浇注式沥青混合料流变性的黏性系数和弹性系数.同时，通过与常用钢桥面铺装材料（SMA10和EA10）的对比研究，分析了不同沥青混合料动态模量、黏性系数和弹性系数随温度的变化规律.结果表明：GA10的黏弹性转变温度为40℃，高于EA10和SMA10；在试验温度范围内，GA10的黏性系数大于EA10，弹性系数小于EA10；当温度超过30℃时，GA10黏性系数大于SMA10，弹性系数小于SMA10. |

| Abstract: |
| The rheological properties of gussasphalt mixture was studied by means of dynamic modulus test. The analysis of the dependence of the dynamic modulus and phase angle to the temperature and frequency, and the viscosity coefficient and elastic coefficient was used to characterize the rheological properties of gussasphalt mixture. The dynamic modulus, viscosity coefficient and elastic coefficient of GA10 at different temperature were compared with EA10 and SMA10 For GA10, its viscoelastic transition temperature is 40℃，higher than that of EA10 and SMA10, its viscosity coefficient is greater than that of EA10, its elastic coefficient is less than that of EA10 Compared with SMA10, when temperature excess 30℃, its viscous coefficient is bigger, while its elastic coefficient is smaller. |
