Multiple Choice

Select material usage: Which statement is true?

Explanation:
Understanding where a given embankment material can be placed depends on its engineered properties and the project specs. If the material has been tested and approved for multiple roles and layers—subgrade, foundation, and various fill or base courses—it can be used throughout the embankment, provided it meets requirements for stability, compaction, drainage, and durability. This is why the statement that it can be used anywhere in the embankment is the best answer: it reflects the material’s approved versatility when design criteria are satisfied. The other ideas imply restrictions that would only hold if the material didn’t meet those criteria or the spec forbids it; with proper testing and approval, those restrictions aren’t mandatory.
