The 8302-5 road roller comes with two sprinkler systems, providing large ballast capacity and ground pressure adjustment. It is applicable to compacting ground surface of asphalt, and base or sub-base layers of various cohesive or non-cohesive materials. As the road roller makes full use of eleven-wheel oscillation, it can achieve high compacting performance.
