Synergetic Effect of Multi-Dimensional Nanomaterials on Aging Resistance of Asphalt
CODEN: JTEVAB
Abstract
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.
