摘要
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。
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.
