Recycled asphalt mixture and preparation method thereof

The invention relates to a recycled asphalt mixture and a preparation method thereof. The asphalt mixture comprises, by mass, 70-90% of recycled asphalt pavement materials, 1-3% of modified asphalt materials, 1-3% of additives and the balance modified stone, wherein the total quantity of the raw materials is 100%. The preparation method of the recycled asphalt mixture includes the steps that the recycled asphalt pavement materials are heated to 100-120 DEG C and blended, then the modified stone is added for blending, the modified asphalt materials and the additives are added, the mixture is mixed at the temperature of 80-115 DEG C, and then recycled asphalt mixture is prepared. The blending ratio of the recycled asphalt pavement materials in the recycled asphalt mixture is high and is increased by about three times compared with the blending ratio of 15-30% specified in present technical specifications, and the utilization rate of the recycled asphalt pavement materials is increased. 本发明涉及种再生沥青混合料及其制备方法。本发明的沥
