Abstract

This paper starts from the research status of SBS modified asphalt aging and regeneration mechanism at home and abroad , and summarizes the performance change law and regeneration mechanism of SBS modified asphalt. Asphalt aging is the main factor that affects the durability of asphalt pavement, and then reduces the service life of the pavement. Through the analysis of the aging status of SBS modified asphalt, the performance change law of aging SBS modified asphalt is analyzed from the microscopic and macroscopic perspectives. The influence factors of multiple aging, rejuvenating agent and regeneration method on the regeneration mechanism of aging SBS modified asphalt . The study of asphalt performance provides reference and reference.
