Long-Term Performance of Flexible Pavement Structures in a Changing Climate
Bibliographic record
Abstract
Climate changes may cause an increase of precipitation in the Province of Quebec over the next decades. As the performance of flexible pavement structures is closely related to moisture content of soils and aggregates, these structures can be considered vulnerable to climate changes. In order to quantify the effect of future precipitations increase on the pavement service life, this research project was based on a three steps approach: 1) Establishment of a relationship between precipitations and water content in the subgrade layers; 2) Establishment of the relationship between soils water content and soils mechanical properties, quantified with the resilient modulus and the permanent deformation behaviour; 3) Quantification of the effect of increased precipitations on pavement life, based on modification of their mechanical behaviour due to water content increase. For the example considered in this paper, it was found that the service life of pavement structures submitted to future climate may present a service life reaching 0.72 times the service of actual pavement structures. These results vary depending on the soil and damage types considered. (A) For the covering abstract of this conference see ITRD record number 201310RT334E.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
