Abstract
The suitable load transfer between adjacent concrete slabs in transverse joint is influenced by various parameters. In this paper, the influence of different diameters and spacing of dowel bars on the slab interaction was considered. Calculations were carried out with application of 3D finite element method. Verification of the model was performed with the concrete pavement in Poland. Results of these calculations were compared with falling weight deflectometer studies. Calculations of stress concentration around dowel bars for different conditions and parameters enabled to determine a relationship between load transfer efficiency (LTE) and vertical compressive stresses in the concrete slab. It was found that application of dowels with small diameters can promote damages in the concrete slab because of concentration of vertical compressive stresses under the dowel bar. The found relationship enables to determine stresses in concrete under the dowel according to its diameter and LTE.

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
