[0035] As a technical optimization solution of the present invention, the provision of the roller 21 and the pushing handle 22 facilitates the operator to push the device to move.

[0036] The working principle and use process of this utility model:

[0037] First, the operator adds foamed asphalt into the storage barrel 11 through the feeding port 20, then starts the heating ring 16 to heat the asphalt, and starts the power motor 17 to make the circular shaft 18 drive the stirring blade 19 to rotate to prevent the asphalt inside the storage barrel 11 from cooling down and agglomerating. Then, the asphalt pump 12 is started to extract the asphalt inside the storage barrel 11 through the extraction pipe 13, and then spray it onto the road surface through the discharge pipe 14 and the spray pipe 15 to spray the road surface.

[0038] At the same time, the operator starts the driving motor 3 so that the rotating shaft 4 drives the elliptical rod 23 to rotate, and pushes the tamping block 7 to move upward under the limiting effect of the fixed plate 5 and the movable plate 6. When the elliptical rod 23 leaves the outer surface of the tamping block 7, the tamping block 7 will hit the asphalt layer under the action of gravity to compact it. At the same time, during the movement of the device, the flattening roller 10 will rotate to flatten the road surface, so that spraying and compaction and flattening are carried out at the same time. Finally, the operator pushes the pushing handle 22 to smoothly advance the device along the sprayed road surface.
