The role of small Road Rollers in earthwork or oil surface compaction

Small-scale road rollers mainly refer to compaction machines of more than 3 tons and less than 10 tons. They are mainly divided into single-drum and double-drum rollers in structure. In recent years, rubber rollers of about 5 tons and hollow or solid bump rollers have appeared one after another. , The basic system solves the compaction problem of earthwork, gravel, sand and gravel mixture and oil surface.

In view of the overall structure of the small road roller, no matter which field it is used for compaction, it basically plays the role of an auxiliary. Afterwards, when encountering green belts or sidewalk sections, a 3-ton double-drum road roller will be used in conjunction with the need to welt or close the side and compaction.

Up to now, China has a large number of rural infrastructures that need to be upgraded. During the process of laying narrow roads or roads, it is inevitable to meet the needs of trench backfilling or water conservancy projects. The vibration of micro-small single drums under 10 tons can play its advantages. Backfilling and compaction can be performed for trenches with a width of 0.5 meters to 1.5 meters, but the thickness is not recommended to exceed 25 cm.
