I. Speed Control Based on Construction Stage
Initial Compaction Stage: Use static compaction, controlling the speed at 1.5-2.5 km/h (1.5-1.7 km/h for initial compaction of cement-stabilized soil base courses) to ensure initial material stabilization.
Secondary Compaction Stage: Speed can be increased to 2-6 km/h; 3-6 km/h is recommended for vibratory rollers to enhance compaction.
Final Compaction Stage: Speed slightly reduced, such as 2.5-3.5 km/h, to ensure a smooth surface.
II. Speed Adjustment Based on Soil Type
Clay/Soft Soil: Low speed (8-12 km/h) is required to avoid the "springy soil" phenomenon.
Sand/Rock Fill: Medium speed (10-15 km/h) is acceptable, utilizing impact force to compact deeper layers.
Asphalt Pavement: 8-12 km/h is required during crushing to reduce damage to the equipment from recoil.
III. Speed Selection Based on Roller Model
Impact Roller: 12-15 km/h recommended for earthwork foundations, such as the 25KJ model.
Vibratory Roller: 3-6 km/h for normal operation; heavier equipment can be operated at a higher speed.
Small Rollers: Such as 1-ton walk-behind (hydraulic transmission) or 3-ton ride-on (0-9.5 km/h), speed needs to be adjusted according to the compaction width and vibration force.
IV. Other Precautions
Safety Limitations: Speed ≤ 8 km/h near slopes or structures.
Environmental Factors: Speed should be reduced under high temperature or high humidity conditions.
