摘要
对橡胶-脱硫胶粉共混改性沥青混合料的路用性能进行研究,结果表明共混胶粉具备较好的黏性及温度稳定性,其性能优于单掺橡胶改性沥青或单掺脱硫胶粉改性沥青。同时通过电镜扫描、差示扫描量热仪等从微观层面探究共混胶粉的改性机理。
The road performance of rubber-desulfurization rubber powder blend modified asphalt mixture is studied.The results show that the blend rubber powder has good viscosity and temperature stability,and its performance is better than that of rubber-desulfurization rubber powder blend modified asphalt or desulfurization rubber powder blend modified asphalt.Through scanning electron microscopy,differential scanning calorimeter test,from the microscopic level to explore the modification mechanism of the blend powder.
