Abstract: The biomass regenerant can effectively dilute and reduce the viscosity of the aged asphalt. At the same time, the biomass regenerant overcomes the technical disadvantage of the mineral oil regenerant, can effectively reduce the emission of toxic and harmful gases, and is greatly beneficial to resource conservation and ecological environment protection. In this paper, the self-developed biomass regenerant (SW-1) is used to restore and improve the performance of aged asphalt. At the same time, three other mineral oil regenerants (ZS-1, ZS-2, ZS-3) are used as comparisons. Analyze the actual effect of the regenerant to improve the performance of the recycled rubber compound. The research data shows that the effect of biomass regenerant onimproving the performance of aged asphalt has certain technical advantages compared with mineral oil regenerant.
