How does the rolling speed of Single Drum Vibratory Rollers affect the compaction effect?

1. Compaction uniformity: Too fast a speed may lead to uneven compaction, with some areas undercompacted and others overcompacted. This is because the vibration and pressure applied by the roller to each point are not applied for a sufficient time during fast rolling.
2. Energy transfer: Slower rolling speeds can transfer vibration energy more fully to the compacted material, increase the friction and interlocking force between material particles, and thus improve the compaction effect.
3. Surface quality: Too fast a speed can easily cause an uneven surface, with waves or ruts; while appropriate low-speed rolling helps to obtain a smoother surface.
4. Compaction depth: A lower rolling speed helps to transfer vibration energy to deeper materials and improve the compaction of the deep layers; high-speed rolling may concentrate the energy on the surface, affecting the compaction effect of the deep layers.
5. Construction efficiency: Too slow a speed will reduce construction efficiency, but in order to ensure compaction quality, the compaction effect cannot be sacrificed by simply pursuing speed.
