Synergetic effect of multidimensional nanomaterials on aging resistance of asphalt

The effect of different nanomaterials on the aging resistance of asphalt was investigated. Three types of nanomaterials, organic expanded vermiculite (OEVMT), nano zinc oxide (ZnO), and multi-dimensional nanomaterials composed by OEVMT and ZnO, were compared. The results show that the single nanomaterial (OEVMT or ZnO) can only enhance one of the abilities to resist thermal-oxidative aging and ultraviolet aging, whereas the multi-dimensional nanomaterials can improve both types of aging resistance effectively. Moreover, compared with the single nanomaterials, the multi-dimensional nanomaterials under the same content show an excellent synergetic effect on thermal-oxidative antiaging ability and have the equivalent ultraviolet aging resistance.
