What are the effects of too high or too low vibration frequency of the roller?

Too high vibration frequency:
1. Excessive surface crushing: It may cause excessive crushing of the surface of the compacted material, especially for brittle materials, which will affect the surface flatness and quality.
2. Energy waste: Too high frequency may not effectively transfer vibration energy to the deep soil, resulting in energy waste, while increasing mechanical wear and energy consumption.
3. Impact on operator comfort: It generates large vibration and noise, reduces the operator's work comfort, and may even have a certain impact on their health.
Too low vibration frequency:
1. Low compaction efficiency: It is impossible to provide enough vibration times per unit time, which prolongs the compaction operation time and reduces construction efficiency.
2. Insufficient compaction depth: It is difficult to transfer vibration energy to the deep soil, resulting in poor deep compaction effect, affecting the stability and bearing capacity of the foundation.
3. Uneven compaction: It may cause uneven compaction of materials, insufficient compaction in some areas, and affect the overall project quality.
