   Vibrating wheel diameter and the static line pressure, the static line pressure is high, vibration wheel ft must also be large. However, the relationship between the diameter of the vibrating wheel and the static line pressure is more stringent than the compaction of the compaction soil.
    Number of vibration wheels and drive form
    The compaction function of the double-wheel vibratory roller is twice that of a single-wheel vibratory roller. Two simultaneous vibratory tandem vibrators are compared to tandem vibrators with only single-wheel vibrations. To achieve the same degree of compactness, the number of rollers required for the former is less. Therefore, the former high productivity.Double Steel Roller - Road Machinery Equipment Manufacturers - Doan Machinery

    Experiments show that the productivity of single-wheel vibration is 80% lower than that of double-wheel vibration when rolling with tandem vibratory roller, and about 50% lower when rolling asphalt mixture.
    Two-wheel vibratory roller and single-wheel vibratory roller compared to the following advantages: to achieve a higher degree of density; to achieve the required density, the required rolling times less; compaction efficiency is higher; the lower temperature Asphalt mixture has a good compaction effect.
    Vibratory roller passive wheel rolling when the rolling layer to make the surface of the push, the front produce bow wave, the back of the ripple. With the active vibration wheel rolling than with the passive vibration wheel can greatly reduce the amount of surface displacement, increase the smoothness of the road. Therefore, in the rolling operation, it is necessary to make the Bian moving wheel in front, the passive wheel in the back, or mining full drive, full vibration of the roller, which can greatly improve the compaction performance and compaction efficiency.
