Clay Soil Grading
Clay grading depends strongly on working condition. Material that is too dry can resist cutting and form clods; material that is too wet can smear, rut and lose its intended shape.

Plan the surface handover
What to verify
Watch for rutting, smearing and large buried clods.
Material roles matter as much as surface levels. Growing medium, structural fill and pavement aggregate should not be treated as interchangeable simply because all can be moved by a scraper. The preparation and acceptance method must follow the intended layer.
The useful moisture condition depends on the soil and task; no universal percentage is specified.
