What is a layer of 6 inches compacted thickness for full width called?

Explanation:
The term for a single, compacted layer laid to a fixed thickness across the entire width is a lift. In earthwork and pavement work, material is placed and compacted in lifts to a specified thickness—often 6 inches (about 150 mm)—to ensure uniform density and proper compaction throughout the strip. A full-width lift helps achieve consistent strength and settlement control. The other terms aren’t used to describe this specific, compacted layer: a layer is a general deposit, a bed is typically a foundational or natural layer, and a plinth is a raised base for a structure.
