Abstract
The Canadian highway bridge design code provides dimensions and reinforcement detailing of concrete bridge barriers reinforced with glass fiber–reinforced polymer (GFRP) bars. However, there are no guidelines on the repair of such concrete elements in case of damage caused by vehicle accidents. Therefore, the main objective of this study is to evaluate the feasibility and efficiency of available techniques to repair damaged GFRP-RC bridge barriers. To fulfill this objective, three full-scale, 6.0-m-long, PL-2 concrete bridge barriers, totally reinforced with GFRP bars, were constructed and tested under an equivalent static load, simulating a vehicle crash test. Two different repair techniques, planting and near-surface-mounted (NSM) fiber-reinforced polymer (FRP) bars, were used to repair the damaged barriers. Repaired barriers were retested under similar conditions to evaluate the effectiveness of the repair techniques. It is concluded that the repaired GFRP-RC bridge barriers achieved similar capacities to their counterpart control (undamaged) barriers.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
