Based on their operating principle and design, road rollers are mainly divided into three categories:
Static rollers: Rely on their own weight to complete compaction. They are primarily used for base construction and preliminary site leveling. They are suitable for final compaction of asphalt pavements and thin soil layers. They offer high compaction uniformity but lower efficiency.
Vibratory rollers: The drum has a built-in vibration mechanism that generates high-frequency vibrations, significantly improving compaction efficiency. This high-frequency vibration enhances particle reorganization and is particularly suitable for asphalt pavements and loose soils. They are also suitable for non-sticky materials such as sand, gravel, and crushed stone. Compaction depths can reach 0.3-0.5 meters.
Pneumatic rubber-tyred rollers: Equipped with rubber tires, they utilize the elasticity of the tires to provide uniform rolling. They are suitable for fine compaction and surface finishing of asphalt layers.
Rollers can be categorized into single-drum, double-drum, caster-type, and small "mini" models. The selection should be flexible based on the nature of the project.
To optimize compaction results and ensure construction efficiency and equipment life, the following parameters must be considered:
2.1 Operating Weight
The higher the axle load, the greater the compaction force. Large projects require heavy-duty rollers (e.g., 20-ton rollers), while smaller projects require lightweight models.
2.2 Vibration Characteristics (applicable only to vibratory rollers)
These include amplitude, frequency, and excitation force. For example, the XCMG XS143 vibratory roller has a nominal amplitude of 0.88–1.86 mm and an excitation force of 225–305 kN.
2.3 Traction and Gradeability
If the project has undulating terrain or steep slopes, models with high gradeability and strong traction should be prioritized.
2.4 Travel Speed
The balance between efficiency and speed control requires adjustment based on the working conditions.
2.5 Watering System Configuration
Especially during asphalt construction, a drum wetting system prevents asphalt sticking. Some smaller models are equipped with a three-stage filtration system for precise control and easy maintenance.
2.6 Driving Comfort and Additional Features
This includes excellent visibility, an air-conditioned cabin, lighting, and shock absorption features, ensuring safe and efficient operation, which is particularly important during long construction periods.
3.1 Selection by Project Type
Highway/Railway Roadbed: A 30-32kJ triangular impact roller is preferred. The impact energy must match the fill thickness (increase the energy by 10kJ for every additional meter of fill).
Municipal Roads/Parking Lots: A 25kJ vibratory roller or tire roller is recommended, balancing cost and shallow compaction requirements.
Existing Road Reconstruction: Pentagonal impact rollers (high frequency) are more suitable for breaking cement slabs, while triangular rollers (concentrated energy) are suitable for roadbed reinforcement.
3.2 Soil Adaptability Analysis
Clay/Collapsible Loess: Requires a high-frequency, low-amplitude vibratory roller or an impact roller with a capacity of 30kJ or above to avoid the "spring soil" effect.
Sand and Gravel Mixture: Choose a 25-30kJ impact roller. Excessive impact energy can easily lead to aggregate breakage.
Based on multiple industry reviews and popularity rankings, the following brands have high credibility and market recognition and are worthy of priority consideration:
XCMG, LiuGong, and Sany Heavy Industry (SANY): Ranked among the top three domestic roller brands in terms of popularity and sales for many consecutive years, they possess comprehensive R&D and service capabilities.
BOMAG, HAMM, and Dynapac: Internationally renowned compaction machinery manufacturers with advanced technology and a comprehensive product line, suitable for large-scale or high-standard projects.
XGMA, Shantui, etc.: Domestic brands offer mature technology, comprehensive service, and excellent value for money.
5.1 Compaction Process Optimization
For asphalt pavement: The temperature difference between the initial compaction (vibration), secondary compaction (tire), and final compaction (static compaction) must be controlled within 20°C.
For impact compaction: Adjacent wheel tracks should overlap by 1/3 of the wheel width. When operating on slopes, the drive wheels should always be positioned below the slope.
5.2 Safety Red Lines
The safe operating distance for impact rollers should be ≥ 10 meters. Vibration damping trenches should be provided near adjacent buildings.
The speed limit for slope operations is 8 km/h. Impact mode is prohibited on sharp curves.
Suggested Procurement Steps:
6.1 Clarify the Construction Requirements: Determine the compaction target (e.g., soil, gravel, asphalt, etc.), construction area, terrain slope, and construction environment.
6.2 Select a suitable model: Consider weight, construction type (vibration/static roller/rubber roller), sprinkler system, and comfort requirements.
6.3 Brand and After-Sales Evaluation: Prioritize brands with a strong service network and parts supply to ensure convenient repair and maintenance.
6.4 Test Drive and Performance Testing: If conditions permit, conduct on-site testing or refer to existing user feedback.
6.5 Consider Financing and Budget: Appropriately evaluate financing options (such as equipment loans, lease financing, etc.) to control cash flow.
