[Purposes] This work aims to study the comprehensive regeneration effect of multiple materials compound preparation of asphalt recycling agent on aged asphalt in depth. [Methods] Tung oil, plasticizer, tackifying resin, and organic montmorillonite ( OMMT ) were used as the primary materials for recycling asphalt. The softening point, 25 ℃ penetration, 15 ℃ ductility and 135 ℃ viscosity obtained from the regenerated asphalt were used as judgment indicators, and the recycling agent was optimized by orthogonal test design to analyze and determine the optimum ratio of each raw material. Dynamic shear rheometer ( DSR ) and bending beam rheometer ( BBR ) were used to effectively verify the feasibility of tung oil composite asphalt recycling agent to restore the performance of aged asphalt. [Findings] The optimum mass for tung oil composite regenerant components was 25∶5∶2∶3; the tung oil composite asphalt recycling agent can effectively restore the performance of aged asphalt, and the high? and low?temperature rheology was better than that of the matrix asphalt. [Conclusions] The research results can provide a certain basis for the follow?up research on the recovery of aging resistance and microstructure of aged asphalt with tung oil composite regenerant.
