What term describes a single lift of compacted material?

• A. Layer
• B. Bed
• C. Lift
• D. Stratum

Answer: (C)

In earthwork and compaction, a single lift refers to one layer of material that is placed and compacted to a specified thickness and density before adding the next layer. This term directly describes the operational step of compacting a discrete slice of fill, which is why it’s the best choice. Other terms like layer, bed, or stratum are more general and don’t inherently convey the process of compacting a single discrete layer in one pass. In practice, each lift is compacted to target density, inspected, and then the next lift is added to build up to the design grade.
