Zusammenfassung:The invention relates to the technical field of asphalt products, in particular to blended asphalt and a preparation method thereof, and an asphalt mixture and a preparation method thereof. The blended asphalt contains hard component asphalt and soft component asphalt, and the weight ratio of the hard component asphalt to the soft component asphalt is (15-90): (10-85); wherein the hard component asphalt meets the conditions that the softening point is greater than or equal to 46 DEG C, and the needle penetration is less than or equal to 6010 mm; the soft component asphalt meets the conditions that the softening point is less than or equal to 51 DEG C, and the needle penetration is more than or equal to 12010-1mm. According to the present invention, by adjusting the weight ratio of the hard component asphalt to the soft component asphalt, the blended asphalt of different brands can be flexibly obtained, and particularly, the blended asphalt provided by the present invention is used for preparing the asph
