Abstract

fetched live from OpenAlex

A mechanistic approach is used to predict frost heave as a function of climate, subgrade soil properties and pavement design. This is part of the ministère des Transports du Québec's (MTQ) pavement design software and standards. The model and its implementation are presented. It is based on the concept of the segregation potential, and on the thermal balance at the freezing front. Material property variables and models are also embedded for automatic calculation of thermal conductivities, latent heat and other important material parameters. Year to year climatic variability may be considered through a statistical approach. The software has been successfully validated against field measurements and a sensitivity study has been done. A maximum frost heave criterion, based on actual data and experience, is used as threshold design criteria. The program is widely used in practice in the province of Québec.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
