The lower end of the connecting frame is detachably connected with a rolling wheel. The connecting frame is rotatably connected with a cleaning part for cleaning the lower surface of the rolling wheel. The cleaning part includes connecting rods and a cleaning scraper. One end of each connecting rod is rotatably connected to the connecting frame by a pin, and the other end is fixed to the ends of the cleaning scraper along the length direction. The controller is electrically connected to the gas cylinder and the test trolley.

[0006] Further, two holes are provided on the connecting frame for fixing the connecting rods. The two holes are symmetrically arranged. The connecting rods are fixed by inserting the rods into the holes.

[0007] Further, a rocking rod is fixed to the lower part of the connecting rod.

[0008] Further, the shaking rod is wound with heat insulation material.

[0009] Further, the cleaning scraper is an arc plate, and the arc of the arc plate is same as the arc of the lower surface of the roller.

[0010] Further, the cleaning scraper is separated from the lower surface of the roller when the cleaning scraper is not in operation.

[0011] The asphalt mixture rut sample forming machine has the advantages that:

[0012] When the asphalt mixture adhered to the lower surface of the roller is cleaned, the roller is lifted by the controller, and the roller is separated from the asphalt sample in the sample disc, so that subsequent operation is facilitated. BRIEF DESCRIPTION OF DRAWINGS
