Assessment of Textured Epoxy-Coated Rebars in Concrete for Chloride Induced Corrosion

Textured-Epoxy coated rebar (TEC) differs from conventional Epoxy coated rebar (ECR) due to its rougher exterior surface – which aims to reduce cracking in concrete and development length. However, no studies have investigated the long-term corrosion response behavior of both TEC and ECR when subjected to service-level bridge deck displacement criteria. This study utilizes Non-Destructive Testing techniques such as Half-Cell Potential (HCP), Ground Penetrating Radar (GPR), Ultrasonic Pulse Velocity (UPV), and Linear Polarization Resistance (LPR) to characterize the corrosion response behavior of service-level stressed TEC and ECR reinforced concrete samples subjected to a realistic chloride environment.
