When leveling, how many scarifying passes are typically made?

When leveling with a road grader, it is typical to make three scarifying passes. This approach allows for better material mixing and more effective depth control. The first pass helps to break up the surface material, introducing air and breaking down clods. The second pass ensures that the loosened material is further broken down and brought up to the desired grade, while the third pass is used for fine-tuning and making final adjustments to achieve a smooth and uniform surface.

Three passes strike a balance between efficiency and thoroughness, ensuring that the roadbed is prepared adequately for subsequent grading and compaction processes. Making too few passes might result in an improperly prepared surface, which could lead to issues with drainage and stability in the finished road.
