1. There are ultra-high small curved road sections, which should be rolled from the inside to the outside, from the lower part of the subgrade to the higher part of the subgrade, to form a one-way ultra-high cross slope.
2. The driving wheel of the roller should be behind when rolling the ramp. When going uphill, the rear driving wheel can bear the driving force provided by the ramp and the machine itself, while the front wheel performs preliminary compaction on 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 road roller is offset by the braking of the driving wheel. Only the mixture rolled by the front wheel has the ability to support the rear driving wheel to generate shearing force.
3. During operation, the road roller should start to vibrate first, and stop vibrating first and then stop when stopping to avoid in-situ vibration.
