How to improve the compacting effect of small road roller?

Nowadays the use of small road rollers is very common. We generally use small road rollers to compact and level the road after the road has just been built to prevent it from being uneven. However, we will find that after the road is finished, The smoothness of the road is not good, which is mainly related to the operation of the machine. The question is, how should we improve the compaction effect of the small road roller?

1. Regardless of whether it is rolling uphill or downhill, the driving wheels of the small road roller should be behind. This has the following advantages: when going uphill, the driving wheel behind can bear the driving force provided by the slope and the machine itself, and at the same time, the front wheel initially compacts the road surface to withstand the large shear force generated by the driving wheel ;When going downhill, the impact force generated by the self-weight of the roller is offset by the braking of the driving wheel. Only the mixture rolled by the front wheel can support the shearing force of the rear driving wheel.
2. When rolling uphill, the roller should start, stop and accelerate smoothly to avoid excessively high or low speed.
3. Before rolling uphill, the mixture should be cooled to the specified lower limit temperature, and then static preloading should be carried out. Only when the temperature of the mixture drops to the lower limit (120°C) can vibration compaction be used.
4. Avoid sudden shifting and braking during downhill rolling.
5. When rolling downhill on a steep slope, light rollers should be used for preloading first, and then heavy rollers or vibratory rollers should be used for compaction.

The above is the method shared with you about improving the compaction effect of the small road roller. I hope it can help you to bring out the full power of the small road roller.
