the method comprises the following steps: the vehicle body (1) is used for being mounted with other equipment, a second motor (61) is operated to further drive a second belt pulley group (62) to move, the second belt pulley group (62) enables the conveyor belt group (23) to move, aggregates are poured into the aggregate frame (21), the conveyor belt group (23) conveys the aggregates to a second connecting pipe (24), then asphalt is poured into the aggregate frame from a throwing port (34) of a throwing box (32), the second motor (61) drives a bevel gear to move to further enable a stirring blade (33) to rotate, and the asphalt is prevented from being solidified while being led in;

step two: the asphalt and the aggregate reach the mixing barrel (42) through the second connecting pipe (24), the second motor (61) drives the third belt pulley set (66) to move and further drives the turbine disc (64) to rotate, so that the mixing barrel (42) rotates on the inner side of the support (41), at the moment, the asphalt and the aggregate are fully mixed due to the fact that the rotating mixing barrel (42) and the trapezoidal blade (48) work in a matched mode, meanwhile, the mixed asphalt mixture is quickly thrown out along the inclined plane of the trapezoidal blade (48) due to the effect of the trapezoidal blade (48), and blockage is prevented;

step three: the asphalt mixture enters a first laying box (51) from a first connecting pipe (52), and simultaneously a first motor (54) is operated to drive a rotating rod (53) to rotate, further, the first helical blades (55) at both ends of the rotating rod (53) are rotated to uniformly discharge the asphalt mixture from the first paving box (51), the connecting hose (512) guides the asphalt mixture into the two second paving boxes (511), the rotating rod (53) drives the spline shaft (514) to rotate through the first belt pulley group (518), further, the second helical blade (517) is rotated to discharge the asphalt mixture from the two second laying boxes (511) uniformly, when the laying width needs to be adjusted, the limit block (58) is pushed to slide in the limit groove (56), the positioning clamping rod (510) moves in different positioning grooves (57), after the width is determined, the positioning clamping rod (510) is clamped with the positioning groove (57) under the action of the positioning push spring (59).
