Which statement correctly describes the FDP edge maintenance requirement?

• A. Edges must be painted.
• B. Edges must be sealed.
• C. Edges may be left uncorrected.
• D. All edges must be cleaned and attached.

Answer: (D)

The key idea here is that edge repairs must form a true, bonded connection to the existing pavement. Cleaning every edge removes dirt, dust, and loose material that would prevent a solid adhesive bond. Attaching the edge means using the proper bonding method (such as tack coat and compatible asphalt) so the new or repaired edge becomes an integral part of the pavement, resisting traffic loads and moisture ingress.

If you only paint or seal edges, you’re addressing surface appearance or moisture skin-deep barriers, not the crucial bond between the repair and the surrounding pavement. Leaving edges uncorrected allows cracks and deterioration to propagate and compromises edge support. Cleaning and attaching ensures a durable, continuous edge that maintains performance and longevity of the roadway.
