Method for mixing asphalt concrete in high-altitude areas

The invention discloses a method for mixing asphalt concrete in high-altitude areas. The method for mixing the asphalt concrete in the high-altitude areas comprises the steps of determining the temperatures of mineral aggregate and asphalt, which are to be heated, according to the temperature of the laid asphalt concrete; mixing the heated mineral aggregate and the heated asphalt; outputting the asphalt concrete whose temperature reaches an outlet temperature; during heating the mineral aggregate, separating out useful dust with particle size of larger than or equal to 0.075 mm and useless dust with particle size of less than 0.075 mm; conveying the useful dust to a mixing plant to be secondarily mixed; and automatically outputting the useless dust to a dust collecting pit in real time to be treated into mud. According to the method for mixing the asphalt concrete in the high-altitude areas, the outlet temperature of the asphalt concrete to be laid is adjusted in real time according to the temperature of the
