To address these challenges, this paper developed an integrated layer interface detection system and a Thickness Condition Index (TCI) using GPR and fuzzy logic. The TCI is designed to support the incorporation of thickness evaluation into pavement condition models. The developed models were tested on twelve diverse road sections from the Long-Term Pavement Performance (LTPP) database.
