What is the difference between the compaction effect of tire rollers and steel wheel rollers?

1. Compaction depth:
Tire roller: The tire of the tire roller has a certain elasticity. During the compaction process, the contact area between the tire and the ground is large, and the pressure distribution is relatively uniform. This enables it to produce a greater compaction effect on the road surface material under a smaller pressure, so that a deeper compaction depth can be achieved. Generally speaking, the compaction depth of a tire roller can reach about 20-30 cm.
Steel wheel roller: The compaction wheel of the steel wheel roller is made of steel, which has a higher hardness and a relatively small contact area with the ground. During the compaction process, the steel wheel roller mainly relies on its own weight and vibration energy to compact the road surface material. Due to the greater hardness of the steel wheel, its compaction depth is relatively shallow, generally around 15-20 cm.
2. Compaction uniformity:
Tire roller: Due to the elastic deformation of the tire, the tire roller can better adapt to the unevenness of the road surface during the compaction process, making the pressure distribution on the road surface more uniform. This helps to improve the flatness and compaction quality of the road surface and reduce uneven settlement of the road surface.
Steel wheel roller: The steel wheel surface of the steel wheel roller is relatively smooth, and local pressure concentration is prone to occur during the compaction process, resulting in uneven compaction. Especially when compacting uneven roads, steel wheel rollers may generate greater pressure at convex or concave places, while the compaction effect at other parts is relatively poor. In order to improve the compaction uniformity, steel wheel rollers usually need to be equipped with advanced vibration systems and automatic leveling devices.
3. Quality of the road surface after compaction:
Tire roller: During the compaction process, the tire roller can make the arrangement between the particles of the road material more compact and form a more stable structure due to the rubbing effect of the tire. This helps to improve the bearing capacity and durability of the road surface and reduce cracks and deformation of the road surface. In addition, the surface of the road surface compacted by the tire roller is relatively flat and the roughness is moderate, which is conducive to improving the anti-skid performance and driving comfort of the road surface.
Steel wheel roller: The surface of the road surface compacted by the steel wheel roller is relatively smooth and has a low roughness. This may not be ideal for some pavements that require higher anti-skid performance (such as mountain roads, highways, etc.). In addition, if the vibration parameters of the steel wheel roller are not set properly during the compaction process, it may cause the pavement material to be over-compacted, making the pavement too hard, thus affecting the flexibility and fatigue resistance of the pavement.
4. Applicable pavement materials:
Tire roller: Tire roller is suitable for compacting various types of pavement materials, including clay soil, sand, gravel, asphalt mixture, etc. Because the compaction depth of tire rollers is large and can adapt to the characteristics of different materials, they have been widely used in road construction and maintenance. Especially for some softer pavement materials (such as clay soil), the compaction effect of tire rollers is more significant.
Steel wheel roller: Steel wheel rollers are mainly suitable for compacting pavement materials with higher hardness, such as rocks, concrete, etc. Because the steel wheel of the steel wheel roller has a higher hardness, it can exert greater pressure on these materials, thereby achieving better compaction effect. In addition, steel wheel rollers also have certain advantages when compacting asphalt pavement, which can make asphalt mixtures more compact and improve the flatness and durability of the pavement.
5. Impact on the surrounding environment:
Tire roller: During the operation of the tire roller, due to the elastic deformation of the tire, a certain amount of noise will be generated. In addition, the friction between the tire and the ground will also generate a certain amount of dust. In order to reduce the impact on the surrounding environment, tire rollers usually need to be equipped with good silencers and sprinkler systems.
Steel wheel roller: During the operation of the steel wheel roller, due to the friction between the steel wheel and the ground, a large amount of noise will be generated. At the same time, the steel wheel roller will also generate a certain amount of dust during the compaction process. In order to reduce the impact on the surrounding environment, the steel wheel roller needs to take effective noise reduction and dust prevention measures, such as installing a muffler and using a dust cover.
