Rules for the operation of rollers
10. Other operating requirements shall comply with the requirements of the hydrostatic roller.No matter whether it is uphill or downhill, the bottom layer of the asphalt mixture must be clean and dry, and the asphalt binding layer must be sprayed to avoid sliding when the mixture is rolled.No matter whether it is uphill rolling or downhill rolling, the driving wheel of the roller should be behind. It has the following advantages: uphill, the driving force behind the driving wheel can withstand ramp and machine provided by their own, while the front wheels were initially on compaction, to withstand the large shear force driving wheel produces; downhill, impact roller weight generated by the driving wheel brake offset, capacity only by the mixture compacted to support the front wheel driving wheel produces shear stress.When rolling uphill, the start, stop and acceleration of the roller must be stable, so that the speed is too high or too low.Before the uphill rolling, the mixture should be cooled to the required low limit temperature, and then static preloading shall be applied. When the mixture temperature drops to the lower limit (120 DEG C), the vibratory compaction will be adopted.The sudden change of speed and braking should be avoided in downhill rolling.The slope is very steep downhill in rolling case, should use light roller pre pressure, followed by heavy rollers or vibratory compaction.
1, when the operation, roller should start in order to shock, the internal combustion engine should be in the medium speed, and then modulation speed.2, speed change and reverse should be stopped first, speed change should reduce the speed of the internal combustion engine.3. No road rollers are allowed to vibrate on solid ground.4, rolling soft roadbed, should be in the case of non vibration rolling 1~2 times, and then vibration, rolling.5, rolling, vibration frequency should be consistent. Yes, you can adjust your vibratory roller, you should adjust the vibration frequency after the operation, not in case there is no vibration, adjust the vibration frequency.6. The adjustment of the reversing clutch, the shock clutch and the brake shall be carried out after the main clutch is disengaged.7, the upper and lower slopes can not use fast files. In turn, including articulated vibratory roller in small turning round rolling, prohibited the use of fast file.8. The roller shall not engage in vibration when driving at high speed.9, stop the vibration should be stopped, and then put the reverse gear in the middle position, the transmission in neutral, and finally pull hands, brake lever, the internal combustion engine idle operation after a few minutes flameout.

In turn, including articulated vibratory roller in small turning round rolling, prohibited the use of fast file.
