Laboratory Evaluation of Concrete-Filled GFRP Dowels in Jointed Concrete Pavements
Bibliographic record
Abstract
For decades, smooth, round, steel dowels have been used to transfer traffic wheel loads across the joints of concrete pavements. These dowels are subjected to shear and bending stresses due to thermal gradients in the pavement slabs in addition to the traffic loads. Over time, the concrete pavement joints become damaged due to the corrosion of the steel dowels as a result of the use of de-icing salts. In order to address both the corrosion and bearing stress problems, large-diameter concrete-filled GFRP tube dowels have been introduced. Experimental work at the University of Manitoba examined and compared the performance of four dowel types including 38 mm epoxy coated steel, 38 mm solid, pultruded GFRP dowels, and two sizes of concrete-filled GFRP tube dowels having diameters of 50.8 mm and 63.5 mm each. For the covering abstract of this conference see ITRD number E211395.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
