In order to study the effect of different rock asphalt contents on the physical and mechanical properties of an asphalt binder and asphalt mixture, the physical and mechanical tests and analysis were conducted. An on-site case was investigated to verify the effectiveness of rock asphalt-modified pavement. The results show that the activation treatment can effectively enhance the molecular polarity of Buton rock asphalt. The “wet process” was used to prepare the Buton rock asphalt-modified asphalt binder, and the high-temperature performance and aging resistance were significantly improved. The modified asphalt prepared by mixing 30% rock asphalt shows the optimum balance between service performance and segregation. The on-site full-scale application of the Buton rock asphalt-modified asphalt pavement showed the good workability and service performance. This research demonstrated the ability of rock asphalt improving asphalt pavement on multiscales. It is helpful for the broader application of rock asphalt in asphalt pavement.
