II. What is Road Roller?
A road roller is a type of engineering machinery that compacts materials such as soil, asphalt, and gravel through its own weight or vibratory force. This road roller equipment is primarily used in the construction of infrastructure such as roads, railways, airports, and embankments, effectively increasing the density and load-bearing capacity of the foundation or pavement, thereby enhancing the stability and durability of the engineering structure.
The road roller can be traced back to the mid-19th century with steam rollers. Over the years, it has developed into a diverse range of equipment with well-defined functions. According to the international standard ISO 6165, road roller equipment is mainly categorized into static, vibratory, rubber-tired, and combination types.
The core functions of a road roller include:
Increasing Material Density: By compacting materials, it reduces the voids between them, making the structure denser and more resistant to compression. Static road roller apply sustained pressure through their weight, while vibratory road roller use high-frequency vibrations to rearrange and tightly bond particles. Impact devices use strong impacts to break down loose structures, forming a more stable foundation. Research shows that proper compaction can significantly reduce material porosity and increase compressive strength by 2-3 times. In highway construction, the rebound modulus of the compacted sub grade can also be doubled, significantly improving road performance.
- Enhancing Surface Smoothness: A smooth surface contributes to improved driving comfort and extends the lifespan of the pavement. Modern road roller equipment is equipped with advanced leveling control systems: tandem road roller can eliminate material accumulation through vibratory compaction, while pneumatic tire roller use the flexible “kneading” action of multiple wheels to smooth out surface marks. By adopting a reasonable combination of compaction processes, the smoothness of asphalt pavement can be controlled within 3mm/4m, effectively reducing fuel consumption by 10%-15%.
- Increasing Road Durability: A dense structure effectively prevents moisture penetration, reducing deformation and cracking caused by rainfall or heavy loads. Data shows that for every 1% increase in compaction, the fatigue life of the road can be extended by about 15%. Modern intelligent rollers are also equipped with compaction monitoring systems to ensure even construction and avoid localized weak points, thereby reducing future maintenance costs by 30%-40%.
III. Detailed Analysis of Road Roller Equipment
1. What is Static Roller？
Working Principle: Static rollers apply continuous static pressure to materials through their own weight, without the need for vibration or impact force.

Advantages: Simple structure, easy maintenance, and a smooth compaction surface.
Limitations: Limited compaction depth; not suitable for thick layers.
Usage Recommendations: Best for fine compaction work on thin surface layers where vibration is a concern.
2. What is Vibratory Roller？
Working Principle: These rollers utilize high-frequency vibration combined with mechanical weight for deep compaction.
Suitable Characteristics: Particularly effective for granular materials (like sand and gravel), with adjustable amplitude and frequency to meet varying compaction needs.
Advantages: Greater compaction depth and high efficiency, suitable for most foundational projects.
Limitations: High vibration and noise levels; not suitable for vibration-sensitive areas.
Usage Recommendations: Ideal for high-grade highways, airport runways, and large-scale industrial foundations.
3. What is Pneumatic Tire Roller?
Working Principle: Achieve uniform compaction through the flexible kneading action of multiple inflatable tires.
Suitable Characteristics: Especially suitable for the final compaction of asphalt mixtures, effectively smoothing out surface marks; tire pressure can be adjusted to accommodate different materials.
Advantages: Smooth compaction with an attractive surface, leaving no significant roller marks.
Limitations: Not suitable for deep compaction; less adaptable to complex foundations.
Usage Recommendations: Suitable for urban roads, bridge decking, and the final compaction of asphalt surfaces.
4. What is Impact Roller？
Working Principle: Generate periodic impacts during high-speed movement of polygonal steel wheels to achieve deep compaction and break up old structures.
Suitable Characteristics: Capable of performing both compaction and breaking functions, with a deep compaction depth, ideal for heavy loads or complex geological conditions.
Advantages: Strong penetration and high compaction efficiency, suitable for high embankments or special foundations.
Limitations: High impact force can affect nearby structures, with elevated noise levels during operation.

6. What is a Sheepsfoot Roller?
A Sheepsfoot roller is a specialized type of compaction equipment designed with large, rounded feet (or pads) on the drum. This unique design allows for effective compaction of cohesive soils, such as clay and silt, by providing a kneading action as the roller moves over the material.
Working Principle: The Sheepsfoot roller works by applying both static weight and kneading pressure from the feet, which penetrate the material to achieve deep compaction.
Suitable Characteristics: Particularly effective for compacting cohesive materials and achieving high density in soil layers, making it ideal for subgrade preparation in road construction.
Advantages: Excellent at reducing air voids and achieving a high degree of compaction in cohesive soils, which enhances stability and strength.
Limitations: Less effective on granular materials and may not provide the same level of smoothness as other roller types.
Usage Recommendations: Best suited for earthworks, embankments, and subgrade compaction where cohesive soils are present, such as in the construction of highways, dams, and foundations.
In practice, relying solely on one type of roller often makes it challenging to complete the entire compaction process. A combination of large, medium, and small rollers, or various types, may be necessary.
IV. Factors to Consider When Buy Road Roller
1. Working Environment
Terrain and Soil Type: The terrain and type of soil are critical in determining the suitable road roller. For cohesive materials, a static roller is recommended. Within static rollers, three-wheel rollers are preferred for subgrade compaction, while two-wheel rollers are used for surface compaction. Sheepsfoot roller is ideal for compacting cohesive soils, particularly for sealing layers in dam constructions, but they are not suitable for surface layers like 2Y8x10B.
2. Compaction Requirements
Different Project Standards: Different projects have varying compaction standards. For non-cohesive materials, a vibratory roller, such as the Qhamch double-drum vibratory roller WD136HF or the single-drum vibratory roller WS125D, should be selected.
3. Material Moisture Content
Low Moisture Content: When the moisture content of the material to be compacted is low and it is difficult to add water, a heavy-duty roller is necessary.
High Moisture Content: Conversely, if the material has a high moisture content and lower dry density requirements, a lightweight roller is preferable.
