A road roller is a compactor-type engineering vehicle used to compact soil, gravel, concrete, or asphalt in the construction of roads and foundations.
Road rollers belong to the category of road equipment in engineering machinery. They are widely used in filling and compacting operations of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, and stadiums. They can roll sandy, semi-viscous and viscous soils, roadbed stabilized soils, and asphalt concrete pavement layers. Rollers use the gravity of the machine itself and are suitable for various compaction operations, making the rolled layer permanently deformed and dense.
A hand push/walk-behind roller is a roller that is supported by both hands for compaction operations. It is required to be easy to operate and lightweight, and suitable for compaction operations in narrow areas and places where large rollers cannot enter.
Applications: Ideal for compacting small areas, such as driveways, sidewalks, and small construction sites.
The small driving-type/ride-on roller is compact and flexible, and its petite body means it does not need to consider the size of the working space. The thickened body shell design makes it stable and reliable to work. The driving operation type has a fast driving speed, which effectively speeds up the progress of the project. The strong vibration force has a good effect of compacting the ground. The body is equipped with an independent vibration switch, which can perform separate vibration compaction and static rolling on the working surface to meet different engineering operation requirements.
Applications: Suitable for large-scale projects, including highway construction, airport runways, and industrial sites.
Small rollers are mainly suitable for small-scale projects and narrow places. This type of roller is particularly suitable for municipal road repairs, rural road reconstruction, garden bridges, and community roads. Due to its small size, it can easily enter narrow areas for operation. In addition, small rollers can also be used as a supplement to large rollers for rolling and maintenance projects to ensure project quality and efficiency.
Applications: Ideal for compacting small areas, such as driveways, sidewalks, and small construction sites
Medium rollers are classified by structural quality, between light and heavy. This type of roller usually has a steel smooth wheel or a cam wheel structure, and can be single-wheel, double-wheel or three-wheel, depending on the number of rolling wheels. The power transmission can be mechanical, hydromechanical or fully hydraulic. Medium rollers
Due to their moderate quality and performance, they are suitable for a variety of road construction and maintenance tasks.
Applications: Suitable for a wide range of applications, including asphalt, concrete, and soil compaction.
Untrained personnel may not understand how to correctly adjust the roller parameters, resulting in poor compaction effect.
Check the various components of the roller, including the engine, brake system, tires, rollers, hydraulic system, etc., to ensure that they are in good working condition.
If the tires are worn or the air pressure is insufficient, it may affect the driving stability and compaction quality of the roller.
Understand the topography, geology and environmental conditions of the construction site and formulate a reasonable construction plan.
Keep a safe distance and it is strictly forbidden to stand or walk within the operating radius of the roller.
There have been cases where people were injured by the rotating roller because they did not pay attention to the safe distance.
Pay attention to the surrounding environment to avoid collisions with other construction equipment or obstacles.
When going downhill, avoid sliding in neutral and use the brake system strictly in accordance with the operating procedures.
Carry out operations in accordance with the specified compaction sequence and overlap width to ensure uniform compaction of the road surface.
If the compaction sequence is chaotic or the overlap width is insufficient, the road surface may be partially compacted.
According to different materials and road surface requirements, select the appropriate compaction mode and pressure.
For example, for soft soil, lower pressure and slower speed should be used for compaction.
Regularly replace wearing parts such as engine oil and filter to ensure the normal operation of the engine.
Failure to replace engine oil for a long time may cause increased engine wear.
Clean the adhesion on the roller in time to prevent affecting the compaction effect.
After the operation, park the roller in a flat and safe place and take protective measures.
