1. Roadbed leveling
Leveling after initial cleaning: In the early stage of road construction, when the site is initially cleaned (such as clearing vegetation, debris, etc.), the grader starts working. It finely levels the ground by adjusting the angle and height of the scraper, removes small bumps and depressions, and creates a relatively flat working surface for subsequent roadbed construction.
Leveling after roadbed earthwork allocation: When the earthwork project is completed after excavation, transportation and allocation, the soil piles on the roadbed are unevenly distributed. The grader can spread these earthworks evenly and accurately level them according to the roadbed slope and height required by the design to ensure the flatness and stability of the roadbed, which is crucial to the bearing capacity and service life of the road.
2. Pavement base construction
Leveling of stabilized soil base: When the road base adopts cement stabilized soil, lime stabilized soil and other structures, the grader can level the paved stabilized soil. It can ensure that the thickness of the stabilized soil base is uniform and consistent, avoiding the situation of local excessive thickness or thinness, so that the base can evenly bear the load transmitted from the road surface.
Leveling of graded gravel base: For graded gravel base, the grader can evenly spread and level the gravel. In this process, by adjusting the scraper action, the gravel forms a suitable slope and density, improves the drainage performance and bearing capacity of the base, and lays a good foundation for the construction of the upper layer.
3. Pavement construction
Preparation before paving asphalt concrete pavement: Before paving asphalt concrete, the grader can finely level and clean the underlying layer (such as the base) again to ensure that the surface of the underlying layer is smooth and clean, which is conducive to the good combination of asphalt concrete and the base, and improves the integrity of the pavement.
Micro-surfacing and slurry seal construction assistance: In the construction of micro-surfacing and slurry seal, the grader can pre-treat the original pavement to make the pavement smoother, and can be used to properly level and modify the surface after construction to ensure construction quality and improve the anti-skid and waterproof performance of the road.
4. Road maintenance and repair
Road pothole repair and leveling: When potholes appear during road use, the grader can assist in repairing them. It can level the pothole filling material to make it flush with the surrounding road surface and restore the flatness of the road.
Application in road widening and reconstruction: When the road needs to be widened or reconstructed, the grader can level the land and handle the earthwork in the new operating area so that the new and old roads can be smoothly connected to ensure the integrity and stability of the road structure.
