      "q": "How much gravel do I need for a 100-foot driveway?",
      "a": "At 10 feet wide and 4 inches deep, about 15 tons — widen the driveway or add a second base layer for heavier traffic, which increases the total accordingly."

      "q": "Should I compact gravel in layers on a long driveway?",
      "a": "Yes, adding and compacting gravel in 2-3 inch lifts prevents ruts and settling far better than dumping the full depth at once, especially on a driveway this long."

      "q": "How often does a gravel driveway need more material?",
      "a": "Plan on topping off with fresh gravel every 1-3 years depending on traffic and drainage, since rain and vehicles gradually displace the surface layer."
