Where must borrow material be from?

• A. On-site stockpile
• B. FDOT approved source
• C. Local on-site borrow area
• D. Any licensed supplier

Answer: (B)

Borrow material must come from an FDOT approved source so the material meets the project’s quality and testing requirements. An approved source has been evaluated, tested, and certified to provide material with the right gradation, moisture-density behavior, and absence of deleterious content for the embankment or backfill. This creates traceability and ensures the material will compact and perform as designed, reducing the risk of settlement, strength loss, or environmental issues. Other sources, like on-site stockpiles or local borrow areas, may be convenient but aren’t automatically acceptable unless they’re on the approved list and have documented test results showing they meet specifications. Simply licensing a supplier doesn’t guarantee that the material fits the project’s exact requirements.
