The incorporation of waste fluid catalytic cracking (FCC) catalysts (WFCs) into asphalt pavements represents an effective strategy for resource utilization. However, the influences composition catalyst and its surface characteristics on performance mortars are still unclear. Herein, five WFCs were selected as powder filler to replace partial mineral (MP) prepare mortars. diffusion behaviors binder components investigated based upon molecular dynamic simulation, was interfacial energy between them. adhesion work values evaluated free theory. A shear rheology test multiple stress creep recovery WFC mortar also conducted. Furthermore, gray correlation analysis (GCA) method employed analyze coefficient with mortar. results showed that exhibited a low high alkaline WFCs. higher than those MP. addition can enhance anti-rutting property significantly. Among WFCs, 2# best improvement effect anti-permanent deformation ability mortar, which may be due large specific area moderate pore width. GCA suggest strongly correlated order > permanent resistance rutting resistance. This study provides both theoretical experimental support application in materials.
