Their high capacity and advanced hydraulic systems make them indispensable for major infrastructure projects.

2. Asphalt Pavers
   Standard asphalt pavers are designed for laying wide, uniform layers of asphalt across large surfaces, such as multi-lane roads or highways. These machines feature advanced controls for precise thickness and width adjustments, ensuring a consistent finish. They are often paired with material transfer vehicles to maintain a steady flow of asphalt and minimize interruptions during paving.

3. Heavy-Duty Rollers
   For large-scale projects, heavy-duty rollers, such as double-drum or pneumatic tire rollers, are used to compact vast areas of asphalt or base materials. These machines are designed to handle high volumes and provide uniform compaction across wide surfaces. Some models feature vibratory systems to enhance compaction efficiency, ensuring the road can withstand heavy traffic loads.

4. Graders
   Graders are critical for creating a smooth, level surface before paving. These machines use a long blade to precisely shape and level the ground, ensuring proper drainage and a stable base. In large-scale projects, graders are used to prepare expansive areas and maintain strict tolerances for road alignment and elevation.

5. Bulldozers
