Abstract
Cement-bitumen treated materials (CBTM) are obtained following full-depth reclamation, and are considered one of the best solutions for pavement rehabilitation from a technical, economic and environmental point of view. Due to the addition of binders and water, CBTM requires time to achieve sufficient strength before reopening to traffic and overlaying with hot mix asphalt. In addition, quality control (QC) is very important to achieve a durable pavement structure. Many agencies in Canada do not have QC specifications or requirements, which limits the use of CBTM. In this paper, the suitability of using the Light-Weight Deflectometer (LWD) for QC purposes in the Canadian context was investigated. Overall, LWD test results showed good reliability for evaluating the stiffening rate of CBTM over time in the Canadian context. Results highlighted that stiffening rate became significant from 4 hours after construction and that traditional laboratory/field measurements were highly variable from one site to another.

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
