The invention discloses a comprehensive maintenance vehicle for road surfaces. The comprehensive maintenance vehicle comprises a vehicle body. The vehicle body comprises chassis and a driving cab, the driving cab is connected onto the chassis, a road rolling mill, a diesel heating drum and a fuel gas heating wall are sequentially arranged on the chassis of the vehicle from the front to the back, an included angle of 10-15 degrees is formed between the diesel heating drum and a horizontal plane of the chassis, a feeding mechanism is arranged on a side of the diesel heating drum, and an emulsified asphalt spraying system is arranged at the bottom of the chassis. Owing to the mode, the comprehensive maintenance vehicle for the road surfaces has the advantages that heating, asphalt regenerative heating, asphalt spraying and compacting functions are integrated with one another, accordingly, the construction efficiency of single equipment can be improved greatly, and the equipment cost and the service cost can be lowered substantially; a compacter of the comprehensive maintenance vehicle can ascend and descend and is flexible and convenient, and accordingly the normal travel speed of the comprehensive maintenance vehicle can be increased.
