Tunnel Operations, Maintenance, Inspection, and Evaluation Manual:
Corrosion protection systems include coatings (e.g., epoxies, powder coatings, paint or galvanizing), high-density concrete cover, tunnel finishes (e.g., tiles, metal panel, or coatings), and cathodic protection systems.
Tunnel Operations, Maintenance, Inspection, and Evaluation
To help safeguard tunnels and ensure reliable levels of service on public roads, the FHWA developed the National Tunnel Inspection Standards (NTIS), the Tunnel Operations Maintenance Inspection and Evaluation
