The invention discloses a low-carbon durable fiber-wrapped wax asphalt reinforced material and a preparation method thereof, and relates to the technical field of road engineering asphalt pavement materials, the fiber-wrapped wax provided by the invention is made of polyethylene glycol terephthalate (PET) fibers, the PET fibers are processed from waste plastic bottles, and the PET fibers are made of a plastic material. Wax adopted by the wrapping fiber is vegetable wax (carnauba wax and/or lignite wax), and the mixing temperature of the asphalt mixture can be reduced by adding the novel fiber wrapping wax reinforcing material into the mixture of asphalt and aggregate, so that harmful asphalt smoke generated in the high-temperature mixing process is reduced, and the low-carbon and environment-friendly effects are achieved. Meanwhile, the vegetable wax can improve the dispersion effect of the PET fibers in the asphalt mixture and improve the reinforcement effect of the PET fibers, so that the rutting resistance
