Abstract

In this paper, a hot regenerant ZZ-1 for asphalt pavement was formulated by compounding waste vegetable oil as the main raw material with aromatic oil and a small amount of additives. The laboratory conducted a comparative test on the Fourier transform infrared spectra, thermal stability, and regeneration effect on short-term aged asphalt between the self-made regenerant and the other two commercially purchased regenerants. The results show that the indicators such as the flash point, mass loss before and after aging, and viscosity ratio of the self-made regenerant all meet the specification requirements, and the regeneration effect is better than the other two commercially purchased regenerants. In addition, the regenerant ZZ-1 with a dosage of 5%–6% can better restore the performance of aged asphalt.
