Warm-mixing regenerant and preparation method of warm-mixing recycled asphalt

The invention discloses a preparation method of a warm-mixing regenerant. The preparation method comprises the steps: mixing and stirring polysorbate, oxidized polyethylene wax, rubber oil and sodiumdodecyl benzene sulfonate to obtain the warm-mixing regenerant. The invention also discloses the preparation method of the warm-mixing recycled asphalt, wherein the warm-mixing recycled asphalt comprises the warm-mixing regenerant, and the preparation method comprises the steps: adding the warm-mixing regenerant into new asphalt, and uniformly mixing at the temperature of 130 DEG C-150 DEG C; andadding a milling material, and continuing to mix for 60-120 minutes to obtain warm-mixing recycled asphalt. The warm-mixing regenerant disclosed by the invention can give consideration to warm mixingand regeneration at the same time, can effectively improve three indexes of the milling material, and effectively reduces the viscosity of the milling material; and the process for preparing the warm-mixing recycled asphalt is
