What is the term for the thickness of each compacted layer?

• A. Lift thickness.
• B. Layer thickness.
• C. Bed thickness.
• D. Compaction height.

Answer: (A)

In earthwork compaction, the thickness of each compacted layer is called lift thickness. This term describes how thick a layer is before it’s compacted, with each lift compacted separately before the next is placed. The idea is to choose a thickness that allows the roller or compactor to achieve the required density throughout the layer; too thick and compaction won’t reach the desired density, too thin and you waste time and effort. Other terms don’t fit because they don’t specifically denote the thickness of an individual compacted layer—the general phrase “layer thickness” isn’t the standard designation for a compacted lift, and “bed thickness” or “compaction height” refer to different concepts in the project.
