Collection Vehicle Payload and Compaction Ratio

The legal fill, and the overload a full body would produce. The worked single axle is legal at 80% of its body; specify chassis and body together so the body governs and the crew can fill it.

in-body density = loose density x compaction ratio; body payload = body volume x that density; chassis payload = gross vehicle weight rating - tare weight; the smaller governs, and the legal fill = chassis payload / in-body density.

Manufacturer ratings against the applicable weight law. Axle-by-axle loading, not just gross weight, is what an enforcement scale checks.

Public arithmetic; the ratings come from the chassis and body manufacturers.

Estimate. AHJ and licensed professional govern.
