PERFORMANCE OF ONTARIO'S FIRST MAJOR REHABILITATION AND OVERLAY PROJECT
Bibliographic record
Abstract
The rehabilitation of concrete freeways has challenged highway authorities for many years. This challenge has been met with the utilization of various techniques such as full and partial depth repairs, diamond grinding and unbonded overlays. In 1989, the Ontario Ministry of Transportation constructed a project to demonstrate the feasibility of these techniques in their jurisdiction, and to monitor the long term performance of the various applications. The project incorporated the use of full depth and partial depth repairs followed by diamond grinding and joint sealant replacement on the northbound lanes (NBL). The southbound lanes (SBL) received an 180 mm thick plain jointed unbonded PCC (JPCP) overlay. The rehabilitation project has now been in service for three years and a number of performance characteristics have been monitored. These include pavement roughness and skid resistance with testing completed on an annual basis while pavement load response, condition surveys and noise emissions testing have been undertaken on an as need basis. The results of this testing and analysis are presented in this paper.

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.
