Technical Field

[0001] The invention relates to the technical field of highway construction equipment, and in particular to a road roller for roadbed rapid reinforcement construction and a construction method. Background Art

[0002] As a commonly used machine for road construction, the main function of a road roller is to compact and flatten the roadbed. However, the working surface width of most existing road rollers cannot be adjusted. For some repaired roads, the repaired position needs to be rolled separately. If the roller of the road roller is wider than the repaired surface, it will be supported by the normal road surface on both sides of the repaired surface, resulting in the inability to touch the repaired surface. When the repaired surface is filled, the roller of the road roller will still be in contact with the part outside the repaired surface, which will cause the weight of the roller to be unable to act completely on the repaired surface. Its weight will be dispersed by the normal road surface, ultimately affecting the rolling effect of the repaired surface. In order to solve the above problems, we proposed a road roller for roadbed rapid reinforcement construction. Summary of the invention
