1. When working, the roller should start first before starting the vibration, and the internal combustion engine should be set to medium speed first before adjusting to high speed.
2. When shifting or reversing, the engine should be stopped first, and when shifting, the engine speed should be reduced.
3. It is strictly prohibited for the roller to vibrate on solid ground.
4. When rolling a soft roadbed, it should be rolled 1-2 times without vibration before vibration rolling.
5. During compaction, the vibration frequency should be kept consistent. For adjustable vibratory rollers, the vibration frequency should be adjusted before operation, and the vibration frequency should not be adjusted without vibration.
6. The adjustment of the reversing clutch, shock absorber clutch, and brake should be carried out after the main clutch is disengaged.
7. When going up or down hills, do not use the fast gear. It is strictly prohibited to use the fast gear during sharp turns, including when using articulated vibratory rollers to roll around small turns.
8. The roller must not engage vibration while driving at high speeds.
9. When stopping the engine, the vibration should be stopped first, then the reversing mechanism should be placed in the middle position, the transmission should be in neutral, and finally the handbrake control lever should be pulled. The internal combustion engine should idle for a few minutes before turning off.
10. Other homework requirements should comply with the regulations for static pressure rollers.
① Whether going uphill or downhill, the bottom layer of asphalt mixture must be clean and dry, and an asphalt binder layer must be sprayed to prevent the mixture from slipping during rolling.
② Whether it is uphill rolling or downhill rolling, the driving wheel of the roller should be at the back. This approach has the following advantages: when going uphill, the rear drive wheels can withstand the slope and the driving force provided by the machine itself, while the front wheels initially compact the road surface to withstand the larger shear force generated by the drive wheels; When going downhill, the impact force generated by the self weight of the road roller is offset by the braking of the driving wheels. Only the mixture crushed by the front wheels has the ability to support the shear force generated by the driving wheels.
③ When rolling uphill, the roller should start, stop, and accelerate smoothly to avoid excessive or insufficient speed.
④ Before rolling uphill, the mixture should be cooled to the specified lower limit temperature, and then subjected to static preloading. Only when the temperature of the mixture drops to the lower limit (120 ℃), vibration compaction should be used.
⑤ When rolling downhill, sudden speed changes and braking should be avoided.
⑥ When rolling downhill on steep slopes, a lightweight roller should be used for pre compaction first, and then a heavy-duty roller or vibratory roller should be used for compaction.
