In order to study the effect of different layered silicates on the anti-aging properties of asphalt mixture, organic montmorillonite (OMMT) and organic rectorite (OREC) were used to prepare layered silicate modified asphalt mixtures. The thermo-oxidative and ultraviolet aging properties of layered silicate modified asphalt mixtures were simulated through indoor accelerated aging tests. The road performance tests were applied to evaluate the anti-aging properties of layered silicate modified asphalt mixtures based on different aging indexes. The results show that both OMMT and OREC can improve the thermo-oxidative aging resistance and ultraviolet aging resistance of asphalt mixtures, and OMMT has a better improvement effect on the aging resistance of asphalt mixture than OREC. Additionally, the high-temperature stability and water stability of OMMT and OREC modified asphalt mixtures are improved, and the low-temperature cracking resistance is also improved after ultraviolet aging.
