The invention discloses a heat-insulation asphalt concrete paving device. The heat-insulation asphalt concrete paving device comprises a paving device body and a heat-insulation device arranged above the paving device body, wherein the heat-insulation device comprises a heat-insulation box and a heater; a feeding hole is formed in the top of the heat-insulation box and a discharging hole is formed in the bottom of the heat-insulation box; the discharging hole is internally provided with a gate valve; the gate valve is connected with an oil cylinder; the heater is connected with the heat-insulation box; and a sector-shaped material pouring device is arranged at the bottom of the gate valve. With the adoption of the manner, the heat-insulation asphalt concrete paving device disclosed by the invention can realize long-time heat insulation of newly added asphalt, and eliminate a phenomenon that pavement construction quality is influenced when the long-time storage temperature of an asphalt mixture is reduced, thereby effectively guaranteeing the paving flatness of pavements.
