What is the minimum length of embankment to be constructed?

• A. 100 ft
• B. 200 ft
• C. 300 ft
• D. 500 ft

Answer: (C)

A single, continuous embankment needs enough length to be placed, compacted, and tested in a consistent way. When you have a long enough stretch, the rolling equipment can follow a stable compaction pattern across the entire section, which helps achieve uniform density and a uniform surface. It also reduces the problem of edge effects at the ends, where compaction tends to be less effective and settlement can be nonuniform. A length that allows a full sequence of passes, proper moisture conditioning, drainage considerations, and quality checks is therefore required. In standard practice problems like this, that practical minimum length is set to a value that comfortably accommodates those steps, which is why the recommended minimum is three hundred feet. Always align with project specs, but the underlying idea is to ensure reliable, uniform compaction and stability over a sufficiently long embankment segment.
