PLANT MIX WARM REGENERATED ASPHALT MIXTURE AND PREPARATION METHOD THEREFOR
The present invention discloses a preparation method of a plant-mixed warm recycled asphalt mixture, which comprises the following steps of: preparing RAP materials, new aggregates, mineral powder, new asphalt and regenerant with a total mass percentage of 100%; heating and stirring the RAP material, adding the regenerant, and then continuing to heat and stir the mixture; placing the product in a development bin for development, wherein a development temperature is 40°C to 150°C, and a development time is 0.5 h to 6 h; mixing, heating and stirring a product with the new aggregate; and mixing and heating a product with the new asphalt, adding the mineral powder, and stirring until the mixture is molded. According to the present invention, a development process of the recycled asphalt mixture is added, which significantly increases the opportunities for mutual permeation, fusion and organic binding between the new asphalt and the old asphalt, enables the new asphalt and the regenerant to fully exert renascence and reconstruction functions in the recycled asphalt pavement material, and improves the recycling effect of the old asphalt, and pavement performances of the recycled asphalt mixture formed can fully reach that of a warm-mixed asphalt mixture produced entirely with new materials.
