采用布洛克菲尔德旋转粘度计(Brookfield)研究测试时间、转速、扭矩等因素对粘度的影响,并对比分析了不同 SBS掺量、不同橡胶粉掺量等对高粘高弹改性沥青的粘温特性。研究结果表明:增粘组分的加入能大幅度提升沥青的粘度,且具备更低的温度敏感性。
採用佈洛剋菲爾德鏇轉粘度計(Brookfield)研究測試時間、轉速、扭矩等因素對粘度的影響,併對比分析瞭不同 SBS摻量、不同橡膠粉摻量等對高粘高彈改性瀝青的粘溫特性。研究結果錶明:增粘組分的加入能大幅度提升瀝青的粘度,且具備更低的溫度敏感性。

The influences of viscosity with testing time,revolving speed and torque were researched by Brookfield viscometer.On this basis,the viscosity-temperature property with different SBS dosage and different rubber powder dosage was analyzed.The results show that the viscosity of asphalt is remarkable improved,and the temperature sen-sibility is lower,after adding tackifying resin to asphalt.
