摘　　要：为了分析硅藻土+橡胶粉复合改性沥青性能粘度的影响因素,对不同的硅藻土和橡胶粉掺量在不同剪切温度和搅拌时间下的复合改性沥青粘度进行分析,结果表明:复合改性沥青粘度随着橡胶粉和硅藻土掺量的增加而呈现增加趋势,并随着剪切温度以及剪切时间的增加呈现先增加后降低趋势。研究成果为复合改性沥青制备工艺提供参考。In order to analyze the influencing factors of the performance viscosity of diatomite ＋ rubberpowder composite modified asphalt, the viscosity of composite modified asphalt with different diatomite andrubber powder contents under different shear temperature and mixing time was analyzed. The results havedemonstrated that the viscosity of composite modified asphalt shows an increase as the rubber and diatomitecontents grow, but the increase gradually weakens as the contents continue to rise. Moreover, theincrement first increases and then slows down with the increase of shear temperature and shear time. Theresults may provide a reference for the preparation of composite modified asphalt.
