为改善沥青的路用性能和发展绿色环保型路面材料，制备温拌胶粉改性沥青，应用动态剪切流变试验( DSR)和低温弯曲梁流变试验( BBR)，全面系统研究胶粉细度及掺量对温拌改性沥青的高温流变性能和低温流变性能的影响规律。试验结果表明：温拌改性沥青的高温稳定性能随着胶粉细度的减小和胶粉掺量的增加而逐渐提高；沥青的低温流变性能随着胶粉细度的增大和胶粉掺量的增加而不断改善。

In order to improve road performance of asphalt and develop green environment friendly pavement materials and prepare warm-mix rubber powder modified asphalt, this paper comprehensively and systematically studies the laws of influences on fineness and mixing amount of rubber powder on high-temperature and low-temperature rheological properties of warm-mix modified asphalt by means of dynamic shear rheological ( DSR) test and low-temperature bending beam rheological ( BBR) test. The test results show that the high-temperature stability of warm-mix modified asphalt is improved gradually with decrease of fineness of rubber powder and increase of mixing amount of rubber powder;and the low-temperature rheological properties of asphalt is improved successively with increase of fineness and mixing amount of rubber powder.
