| 摘 要： | 采用动态力学分析方法对基质沥青和TLA改性沥青的高温动态流变性能进行研究,测定了一定温度和频率范围内的动态流变性能参数,并通过分析TLA掺量不同的改性沥青的动态性能参数变化规律来分析TLA对沥青的流变性能的影响,结果表明：加入TLA后沥青复数模量增大,相位角减小,沥青的车辙因子相应增大.

| Abstract: | This paper applies dynamic mechanical analysis method to study the dynamic rheological properties of common asphalt and TLA modified asphalt in high-temperature;and measures the temperature and frequency parameters of the dynamic rheological properties within a certain range;and analyses the impact of the variation of the rheological properties of asphalt TLA through the analysis of different dosage TLA modified asphalt dynamic performance parameters.The results show that: after adding TLA increased asphalt complex modulus,phase angle decreases while asphalt rutting factor increases. |
