| Popis: | Compared with traditional materials, nanomaterial has rich and excellent performance due to the size advantages. If nanotechnology is combined with pavement materials, it is foreseeable that it will have a profound impact on the development of the road. In the study, graphene oxide nanomaterial was added as modifiers to rubber asphalt and its microstructure was characterized. The rheological properties of graphene oxide rubber asphalt and the road performance of asphalt mixture were studied in accordance with the SHRP test. The results showed that graphene oxide could form a dense and stable microstructure with rubber powder and asphalt polymer. As a modifier, it could improve the anti-rutting performance of rubber modified asphalt and was more suitable for heavy traffic. Moreover, it had low sensitivity to temperature and was more suitable for areas with large temperature difference between day and night. The pavement performance of the graphene oxide rubber asphalt mixture had also been greatly improved. |
