Abstract

fetched live from OpenAlex

Les fissures de retrait thermique se produisent à basses températures. L'enrobé bitumineux tend alors à se contracter sous l'effet du froid mais est empêché de le faire sous l'effet de la friction avec le matériau de fondation. Ainsi, l'enrobé accumule une contrainte qui peut dépasser la résistance en tension de l'enrobé et créer une fissure de retrait thermique. Afin de mieux comprendre le phénomène et si possible intégrer cet aspect lors de la formulation des enrobés bitumineux, l'appareil de laboratoire de retrait thermique empêché (TSRST: thermal stress restrained specimen test) a été utilisé pour caractériser les enrobés ESG-10, ESG-14, EB-10C et EGA-10 utilisés dans la province de Québec et ils ont été formulés avec les bitumes PG 58-28, PG 58-34 et PG 64-34. De plus des essais ont été effectués sur les bitumes afin de permettre l'analyse de corrélations entre la température de fissuration obtenue à l'essai de retrait empêché et les caractéristiques des bitumes."--Résumé abrégé par UMI.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
