Abstract In this paper, a kind of asphalt rejuvenator RA with good regeneration and aging resistance was studied, and RB and RC were selected for comparison. The amount of antiaging agent and plasti-cizer was determined by experimental design and analysis. According to the three indexes of re-cycled asphalt and viscosity test, the optimum content of recycled asphalt is 6%. Through dynamic shear rheological test analysis, the results show that three different kinds of regeneration agents can restore the rheological property of aging asphalt, the complex modulus G * of recycled asphalt A1 and phase Angle θ can be close to the level of 70# virgin asphalt. It is found that regenerated asphalt A1 can obtain higher creep recovery rate through repeated creep test analysis of mul-ti-stage stress. The results of low temperature bending creep test show that the self-developed rejuvenator RA can restore the low temperature cracking resistance of aged asphalt. Through the analysis of quality loss, residual penetration ratio and softening point increment of regenerated asphalt, regenerated asphalt A1 has better aging resistance. Keywordsice age 4
