A thin overlay is a non-structural maintenance treatment.

Explanation:
Thin overlays are a surface maintenance treatment. They add a new wearing surface to restore ride quality, seal the pavement, and extend life, but they don’t meaningfully increase the road’s structural capacity or load-carrying strength. Because of that, they’re classified as non-structural maintenance rather than a structural rehab. That’s why the statement is true. If the goal were to improve structural capacity, a thicker overlay or other structural rehab would be needed rather than a thin overlay.
