Temperature field method for asphalt concrete core wall construction in high altitude area

The invention discloses a temperature field method for asphalt concrete core wall construction in a high altitude area. The method comprises the following steps that a lower asphalt concrete layer is laid; the temperature of the lower asphalt concrete layer is detected; if the surface temperature of the lower asphalt concrete layer is lower than 70 DEG C, the concrete out-of-mixer temperature and paving temperature of asphalt concrete to be laid are determined, and the mixing temperature of the asphalt concrete to be laid is adjusted, so that the temperature of the output asphalt concrete reaches the concrete out-of-mixer temperature; the output asphalt concrete is directly laid on the lower asphalt concrete layer at the paving temperature, and an upper asphalt concrete layer connected with the lower asphalt concrete layer in a butted mode is formed; and the above steps are repeated to form an asphalt concrete core wall field effect distribution of temperatures. According to the method, when the surface tempe
