Our 8202-5 road roller is widely used to compact asphalt surface, cohesive or non-cohesive base layers, as well as sub-base layers of various materials. It is characterized by eleven-wheel oscillation, ensuring good compacting effect. In addition, this pneumatic roller utilizes dual sprinkler systems with large ballast capacity. Moreover, the ground pressure can be well adjusted to meet different road construction requirements.
