Long Term Performance of the James Bay Specialized Haul Route in Northern Quebec
Bibliographic record
Abstract
The James Bay Access Road was constructed in 1972-74 to provide access to the James Bay Hydroelectric project on the La Grande River. The 720-kilometre access road was constructed in just 450 days over difficult terrain and was paved in 1975 and 1976. The road was constructed as a private access road for the hydroelectric construction project and has been subjected to intensive truck traffic as it provided access for all cement, fuel and construction materials required for the massive project. Given that the owner was also the sole user, weight restrictions and maintenance requirements were viewed differently compared to a normal highway department perspective. This paper reviews the pavement condition over the past 30 years. This data provides a unique large-scale study of pavement performance when subjected to severe traffic and climatic conditions. As a pavement management system was instituted at the same time, the paper reviews the evolution of that pavement management system over the life of the pavement.

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.
