Luoyang road roller Manufacturers contend that, in highway, railway, airport, hydraulic engineering, and construction projects, road rollers are primarily used to compact subgrades, pavements, embankments, cofferdams, and building foundations. Small‑size road rollers are well suited for compacting confined spaces. Compaction refers to the process by which external forces—through rolling and impact—overcome the friction and cohesive forces between particles of soil, sand, gravel, or asphalt mixtures, causing them to rearrange, draw closer together, and expel water and air. As a result, the friction and cohesion among material particles increase, leading to a denser, more compacted structure.
According to Luoyang road roller manufacturers, compaction involves four processes: rearrangement, filling, separation, and consolidation. Specifically, larger particles are reorganized, reducing the voids between them; smaller particles fill the spaces among the larger ones; and water and air trapped in these voids are expelled. Under external forces, particles may fracture, leading to further compaction. The compactive forces include static pressure, impact force, vibratory force, oscillatory force, and frictional force. Machinery capable of generating these compactive forces is known as a road roller.
According to a roller manufacturer in Luoyang, there are three main types of road rollers: steel‑wheel rollers, rubber‑tire rollers, and vibratory steel‑wheel rollers. In current construction practice, the latter two are more widely used. The primary functions of the roller drum are twofold: first, to achieve the specified compaction density; and second, to smooth and level the pavement surface.
According to the Luoyang roller manufacturer, compaction comprises three stages: initial rolling, intermediate rolling, and final rolling. Final rolling, aimed at eliminating roller marks, is an indispensable step for maintaining pavement smoothness and is typically carried out using steel‑wheel rollers. Of course, if the initial rolling meets the required density, intermediate rolling may be omitted; however, in practice, these three steps are usually retained in most field operations. Steel‑drum rollers are generally used for initial rolling, but they can lead to “flowing” — where the mix ahead of the roller shifts laterally under pressure, potentially resulting in cracks after compaction. Rubber‑tire rollers are also employed for initial rolling, yet, due to the high temperatures at this stage, the mix tends to adhere to the tires, leaving marks that are difficult to remove, which often necessitates subsequent rubber‑tire rolling.
According to the Luoyang road roller manufacturer, the following are important precautions for operating a road roller:
1. After completing the work, the roller should be started before the earthquake; the internal combustion engine should first be set to medium speed, then increased to high speed.
2. Stop the engine when shifting gears or reversing, and reduce the internal combustion engine speed during gear changes.
3. Vibrating the roller on hard ground is strictly prohibited.
4. When compacting soft subgrades, first pass the roller without vibration 1 to 2 times, then proceed with vibratory compaction.
5. According to the Luoyang roller manufacturer, the vibration frequency should remain constant during compaction. For vibratory rollers with adjustable vibration frequencies, the frequency must be set prior to operation; under non‑seismic conditions, the vibration frequency must not be adjusted.
6. Adjustment of the reversing clutch, impact clutch, and brake shall be performed with the main clutch disengaged.
