 mainly used for earthwork and asphalt applications. New construction and repair work for medium and small scale construction projects, on parking lots, sidewalks, cycle paths, playing fields and sports grounds as well as rolling of joints in road construction.

6~10t large vibratory roller with relatively high pressure and solid capacity should be used for national trunk roads and special roads for automobiles.
For the highway below grade 3, or not often compaction work, it is best to equip with about 2t mobile flexible vibration roller.

2. For the cement concrete pavement, the series vibration roller driven by tire can be used;

3. For asphalt concrete pavement, full-drive vibratory roller should be selected;

4. For the bottom layer of high-grade road subgrade, it is better to choose tire roller or tire driving vibration roller for compaction to obtain uniform compaction;

5. When repairing the road surface, the static action roller can be used.

Iv. Selection of pressed materials according to the type:

1. For rock filling compaction, large tonnage roller should be selected to make large block displacement;

2 for clay compaction, it is best to use convex block ramming roller;

3. For the compaction of the mixture, it is better to choose vibratory roller, so as to mix the size of the particles evenly;

4. Heavy vibratory roller should be used for slow rolling for deep compaction, while static action roller should be used for shallow compaction.
