Bituminous mixture transfer car comprises hopper, material inlet helix, material tank body, material tank, first discharge device, moving system, second discharge device, second discharge drive system, hydraulic pressure system, electrical system, power system, driving cap, top, cleaning device, centralized lubricating system, exhaust emission system and discharge holding hopper. The invention improves the copper, material tank body, material tank, first discharge device, second discharge device, hydraulic pressure system, top, centralized lubricating system, and discharge holding hopper so as to increase the combination property index of the set. Meanwhile, the using effect and operating style gets a good improvement relative to the current bituminous mixture transfer car so as to improve the pavement spreading quality.
