The working principle of a road roller is to use its own gravity and vibration to compact various materials, such as soil, gravel, concrete, etc. In highway construction, road rollers are one of the most commonly used compaction equipment. It is usually used to compact the foundation layer, stabilizing layer, and asphalt surface layer of the road surface, in order to improve the compactness and bearing capacity of the road.

Small road rollers play an important role in urban road maintenance. It can quickly repair damaged road surfaces, restore road smoothness and traffic capacity. For small construction areas such as sidewalks and squares, small rollers are equally capable. Its precise compaction ability ensures the stability and durability of construction quality. In bridge and tunnel construction, small rollers can operate flexibly in limited spaces to ensure construction quality. In landscape construction, small rollers can be used to compact the soil in areas such as lawns and flower beds, improving the ornamental and practical value of the landscape.
