Experimental Study on the Effect of CNTs on High Temperature Performance of SBS Modified Asphalt
SBS modified asphalt is widely used in China's road construction,and with continuous in-depth re-search,composite modified asphalt has gradually become one of the main means in improving asphalt perfor-mance.To investigate the high-temperature performance of CNTs in the composite modification of SBS modified asphalt,different dosages of CNTs/SBS composite modified asphalt were first prepared using a high-speed shear apparatus and melt blending method,the influence of different dosages of CNTs on the high-temperature perfor-mance of SBS modified asphalt was studied through Brinell rotational viscosity test and multiple stress creep test.The results indicate that the addition of CNTs can improve the viscosity,high-temperature rheological properties,and high-temperature resistance to rutting deformation of SBS modified asphalt.
