When selecting a suitable road roller machine, there are several key factors to consider. Road rollers play a vital role in different construction environments and materials, and understanding their characteristics can help you make informed decisions. Here are several aspects to focus on when choosing a road construction roller, along with an analysis of soil structure, construction efficiency, and brand options to help you select the best equipment.
I. Choose Road Roller Machine Based on Soil Structure
- Single Drum Vibratory Roller
Suitable for non-cohesive materials such as gravel, crushed stone, sand and gravel mixtures, and sandy soils. Its design allows for even compaction over larger areas, ideal for the initial compaction stages of infrastructure projects.
- Double Drum Vibratory Roller
Better suited for compacting asphalt concrete, sand and gravel mixtures, and dry hard cement concrete. Widely used in high-grade highways, municipal roads, and parking lots, it provides efficient compaction results.
- Static Roller
Suitable for compacting fine soil particles, sandy soil, and asphalt concrete materials. Its heavier weight provides a “iron effect” that smoothens the surface, making it ideal for final compaction of various cohesive and non-cohesive materials.
- Block Vibratory Roller
Can generate high line loads, making it suitable for compacting non-cohesive soils while also effectively handling cohesive soils. Commonly used in highways, mining roads, and large dam foundations.
- Tire Roller
Uses specially designed inflated smooth tires to compact the layer materials. Its flexible compaction effect is superior to rigid rollers, allowing it to adapt to different soil types, especially for high-grade highway surface treatments.
II. Choose Based on Construction Efficiency Requirements
- Static Roller
Relies on its own weight, line load, compaction passes, and speed to demonstrate its compaction ability. Typically suitable for layers not exceeding 25 cm in thickness, with a compaction speed of 2-4 km/h, requiring 8-10 passes to meet standard requirements.
- Vibratory Roller
Uses high-frequency vibrations to apply impact force to the soil, forcing internal particles to rearrange and allowing smaller particles to fill the voids of larger ones. Due to its high impact force, the compaction depth can reach 50-60 cm, with some heavy-duty models exceeding 1 meter. At a speed of 4-6 km/h, only 4-6 passes are needed to achieve the required density, making it 2-3 times more efficient than static rollers.
In colder regions with short construction seasons, vibratory rollers are preferred; while in mountainous areas or loose soil conditions, static rollers are recommended to avoid landslides or collapses caused by the vibratory force, which can hinder construction progress.
III. Choose Based on Construction Procedures
To enhance construction quality and efficiency, a phased approach is often used: After laying the subgrade, start with a vibratory roller for initial compaction, followed by a tire roller for intermediate compaction, and finally a smooth drum roller for final finishing. If conditions are limited or road grade requirements are lower, a single type of roller can be used for all processes. However, if a static roller is chosen, multiple passes will be needed to meet the required density; if a single drum vibratory roller is used, the final finishing should be done without vibration to avoid tire marks on the surface.
