Improvement in construction quality
"Vibratory three wheel roller", oscillatory or circular(normal) vibration is selected by switch at operator station depending on the job conditions. The oscillatory vibration is good for micro thin lift and the circular vibration is effective fot thick layer compaction.
Vibration/oscillation can be selected, All three drums, Front left drums, or front right drums only and the positive compaction of longitudinal joint and compaction is fully covered to the edge of curb of pavement.
Since the three wheel roller does not have overhang, the compactor at job sites adjacent to traffic can be done safety.
Also at the construction spot contiguous to a traffic opening zone, there are also few overhangs of a frame because of three wheel roller, and it reduces a minor collision with the vehicles it is running.
