[0002] Highways are roads connecting cities, urban and rural areas, villages, and industrial and mining bases, built according to national technical standards and approved by the highway authorities. These include expressways, first-class highways, second-class highways, third-class highways, and fourth-class highways, but do not include naturally formed paths in fields or rural areas. They are primarily for automobile travel and meet certain technical standards and facilities. Highways are subject to wear and impact from wheels, erosion and weathering from natural forces such as rainstorms, floods, sandstorms, snow, sunlight, and ice melt, as well as human damage and defects left over from construction. This has led to a gradual decline in highway quality, resulting in cracks. Cracks in highways must be repaired promptly. Crack repair generally involves placing patching materials at the crack. Existing methods of repairing highway cracks are manual, which cannot effectively flatten the cracks, resulting in poor flatness at the repaired areas. Utility Model Content
