Which term refers to each individual layer of fill used to build up an embankment?

• A. Lifts
• B. Strata
• C. Layers
• D. Courses

Answer: (D)

Each individual layer of fill used to build up an embankment is called a course. In embankment construction, material is placed in successive, controlled-thickness layers and compacted before the next layer goes on. This ensures the structure gains the necessary density and stability. The term course specifically denotes each complete layer that’s spread and compacted to the required thickness, forming part of the overall height. Other terms describe different ideas or are too generic for this context: a lift can refer to the act of placing material, while strata is a geological term, and layers is too vague for the standard construction terminology used here.
