Abstract:

The feasibility and limitations of Forward Looking Infrared Radiometer (FLIR) Aerial Technology for detecting fouled ballasts is studied in this project. The method is intended to provide an efficient and ready-to-use approach that can help the railroads detect fouled ballasts in their early stages. Ballast fouling commonly occurs as a result of fine particles clogging off water passage through them. Subsequently, this results in trapped water that often results in poor foundation strength, rotting of the ties, and other ill effects.
