Abstract
In 2005, Saskatchewan Ministry of Highways and Infrastructure (SMHI) piloted the use of crumb rubber modified hot mix asphalt concrete (HMAC) in test sections on a primary highway. Crumb rubber surfacing did not significantly influence the heavy weight deflectometer measured structural performance of the pavement test sections. Ground penetrating radar analysis showed minimal difference in the surface permittivity of the crumb rubber HMAC and conventional SMHI Type 71 HMAC surfacing. A visual inspection of the test sections found that crumb rubber HMAC had a more open texture that appeared to mask the visual identification of transverse cracks. However, thermal and reflective cracks were observed to be present in both surface types. In summary, crumb rubber modified HMAC pavement in Saskatchewan did not yield significant difference in structural or surface condition compared to conventional SMHI Type 71 HMAC surfacing after 3 years of service in the field.

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
