摘要：
To promote the recycling of reclaimed asphalt pavement(RAP), epoxy resin was used to prepare the epoxy-recycled asphalt mixtures. The effect of epoxy resin on the properties of aged asphalt binder was investigated based on the tensile test, flexural creep test, and laser scanning confocal microscopy. The curing characteristics and the mechanical performance of recycled asphalt with different epoxy contents were explored. The results show that the low-temperature performance, ductility, and strength of the aged asphalt binder were significantly improved when the epoxy content reached 40%. The curing time of epoxy-recycled asphalt should be at least 4 d to ensure the formation of good internal spatial network structure.
