Brief introduction to compacting principle of roller     

1, because the asphalt can only achieve the best compaction effect at high temperature, so the compactor should be compacted in the shortest time.

2. Unless the construction is on the very steep operating surface, the driving wheel should face the paver to prevent the accumulation of the non compacted material in front of the steel wheel, which will lead to the transverse cracks of the paving layer.

3, steel road roller should be watering, avoid fresh asphalt adhesion in the steel wheel.

4. Under the static state of the roller, the vibration function is strictly forbidden, otherwise the permanent indentation will be left on the surface of the paving layer.

5. The starting and retrogression of rollers should be slow, or the speed control device should be equipped to prevent the piling up of the paving material before the steel wheel. Heavy duty paver should also pay special attention to, not in the paving layer on the stationary.

6, roller vibration function should not be opened before the machine began to travel. When the back work should be shut down or use the vibration function of automatic speed control system. Because the paving opportunity slows down to a stop in a certain area, and then starts up and accelerates backward gradually, so the vibration will cause greater influence in the same area, which leads to the decrease of paving surface smoothness.

7, in the existence of the transverse slope of the road roller compaction, should be in the low slope of the road surface began to compaction, gradually to high-end compaction.

8. Only the rollers are allowed to stop and turn on the compacted pavement to prevent material accumulation before the steel wheel.

9, is strictly prohibited in the hot asphalt surface parking, because the roller weight causes the indentation.

10, road roller should be parked diagonally and spreading direction. If the roller on the paving surface formed of indentation on driving comfort smaller.
