and step 3: milling in a rutting area, adjusting a driving motor (3), wherein the driving motor (3) works, the driving motor (3) drives a first group of milling cutter discs (34) and a second group of milling cutter discs (34) to mill the asphalt pavement, the vehicle body (1) is poured to the initial milling position of the rutting area, the second group of milling cutter discs (34) are adjusted, so that the distance between the two milling cutter discs (34) in the second group of milling cutter discs (34) on the side away from each other is larger than the distance between the milling cutter discs (34) in the second group of milling cutter discs (34) in the primary adjustment by 1-3mm, and milling parts which are not milled in the rutting area until the asphalt in the rutting area is milled completely;
and 4, step 4: cleaning, wherein workers clean broken stones and waste residues in a track area and the periphery;
and 5: hot melting, namely, hot melting the asphalt material at the edge of the track area to ensure that the asphalt at the edge of the track area is in a molten state;
step 6: filling, namely firstly paving an asphalt material with the particle size of 16-20mm by a worker until the distance between the asphalt material and an asphalt pavement is 10mm, then paving the asphalt material with the particle size of 13mm, enabling the asphalt material with the particle size of 13mm to be at least 2-3mm higher than the surface of the asphalt pavement, and completely filling a planning and milling area;
and 7: rolling, namely repeatedly compacting the asphalt material in the track area to keep the asphalt material flush with the surface of the asphalt pavement, and enabling the upper part of the asphalt material to be smooth and flat without rolling indentations, and compacting the corners of the planing and milling area without loosening;
and 8: and (4) secondary cleaning, namely cleaning redundant materials and residues after rolling.
8. The rut repairing process according to claim 7, wherein in the step 4, in the cleaning process, the asphalt waste inside the rut area is cleaned, then the edge of the rut area is cleaned through a brush until the bottom and the periphery of the rut area are solid surfaces, then floating dust and impurities in the rut area are blown off through an air gun, then the bottom wall and the periphery of the rut area are washed through water, and finally drying is performed.
