Building construction, taking vibratory compactor as an example, illustrates the method of compaction Matters to be attended to?
Roller static pressure 2 times. The overlap wheel width is 1/3 to 1/4, and the rolling speed is 25 to 30m / min. Then crush it 6~8 times with shock. Overlapping rear wheel 1/2, rolling speed 30 ~ 50M / min.
Compaction method has three principles: (1) first light and heavy: (2) first slow, then fast; (3) first low and high;It should be noted that: (1) the time of compaction, soil base must be appropriate water content, asphalt mixture temperature appropriate.(2) the role of the regulator - first slow and stable, is to maintain the new layer without deformation:(3) crown holding by low in high RCC will guarantee;(4) asphalt mixture rolling - watering appropriate, non stick office building, but quickly cool down
