Series type hot air heating device for bituminous pavement and heating control method of device

The invention provides a series type hot air heating device for bituminous pavement and a heating control method of the device. A plurality of hot air heating plates are connected, a heating mode of continuous variable power is utilized, heating power of all heating units is determined, the heating units output different heating power to the bituminous pavement in the driving process, and thus temperature of the surface of the bituminous pavement and temperature at the 4cm depth position are accurately controlled; at the same time, the multiple heating units are switched on, hot air dischargedto the environment by a former heating unit re-enters an air inlet of a next heating unit through a circulating pipeline, the circulating utilization rate of the hot air is further improved, discharging of the hot air carrying harmful gases from the heating units to the surrounding atmosphere is reduced, and the ecological environment is protected. 本发明提供的一种串联式沥青路面的热风加热装置及加热控制方法，通过将多个热风加热板连接起来，利用连续变功率的加热方式，确定了各个解热单元的加热功率，
