Research on the Performance of Asphalt Modified by SBS Rubber and Carbon Nanotube
In this study, by the way of adding functional carbon nanotubes into the SBS modified rubber powder to obtain a new type of composite asphalt modifier. The new modified bitumen was prepared with the asphalt compound modifier. A lot of structure and road performance tests were carried out about the new modified asphalt and its mixture. The results demonstrated that after adding new type of carbon nanotube, the modified asphalt obtained a more stable internal structure; the performance index (softening point, penetration, and ductility) had better performance.
