WARM RECYCLED ASPHALT ADDITIVES, MANUFACTURING METHOD THEREOF AND WARM RECYCLED ASPHALT CONCRETE

JUNG HONG KI

The present invention relates to a warm recycled asphalt additive, a manufacturing method of the warm recycled asphalt additive, and warm recycled asphalt concrete. The manufacturing method of a warm recycled asphalt additive comprises: a first composition manufacturing step of mixing 40-70 parts by weight of asphalt, 0.15-10 parts by weight of a thickening agent, and 0.15-10 parts by weight of an ionization agent in 100 parts by weight of water; a second composition manufacturing step of mixing the first composition and oil having initial boiling point (IBP) of at least 175°C with a weight ratio of 40:60 to 60:40; and an immersion step of immersing 50-150 parts by weight of the second composition in 100 parts by weight of a porous inorganic material. The warm recycled asphalt additive can recover a function of asphalt as a binder, and can be simply manufactured through a porous inorganic material including moisture.
