Study on the Road Performance of Polymer Composite Modified Asphalt with Different Carbon Nanotube Content
This paper studies the carbon nanotubes addition process and carbon nanotubes doping in the preparation process of carbon nanotubes/SBS composite modified asphalt,the research results show that the preparation process of solution blending and mechanical blending can help the carbon nanotubes material dispersion in SBS modified asphalt,at the same time,the doping of CNTs should be controlled.The results of the study showed that the preparation process of solution blending and mechanical blending could help the dispersion of CNTs in SBS modified bitumen.On this basis,the road performance research results of composite carbon nanotubes/polymer modification show that composite carbon nanotubes/polymer modification can perform better than individual CNTs modification and SBS modified asphalt.Modification can effectively and significantly improve the high temperature anti-rutting performance and fatigue performance of modified asphalt.
