1. The road roller plays a very important role in the edge areas of some ditch corners. In fact, when compacting the cement asphalt at the corners, it is often inconvenient to use a large road roller in this case. The edge area will also be very inflexible, and in this case, the advantage of using a small roller is obvious.
2. In many municipal constructions, when maintaining roads, road rollers need to stratify and compact the cement stable layer on the road. At this time, it is very convenient and effective to use small road rollers.
3. When the road roller is used to backfill the pipelines, passages, bridges, and other structures on the highway, the road roller will definitely easily damage the structure of these facilities, and this problem will not occur with a small road roller.
