| Abstract: | In this paper, the performance of graphene composite rubber modified asphalt (GRA) pavement was studied based on the engineering example of the Liu-Dun highway test section in Gansu province. The performance of GRA was analyzed by routine tests, multiple stress creep and recovery (MSCR) test, dynamic shear rheometer (DSR) test and other methods, and the road performance of GRA mixtures was also studied. The results show that compared with SBS modified asphalt, the penetration of GRA is reduced by 12.7%, the softening point, high temperature stability and high temperature resistance to deformation are equivalent, and the resistance to stress deformation and stress sensitivity are improved.Compared with rubber SBS modified asphalt, GRA has an increase in softening point of 14.1%, elastic recovery by 6.5%, equivalent penetration, high temperature stability and high temperature resistance to deformation. Compared with SBS modified asphalt mixture, GRA has better road performance. The on-site mixture is easier to compact, and has less water seepage and higher strength, but the structure depth is reduced. |
