SIX YEARS EXPERIENCE WITH EXPERIMENIAL CONCRETE PAVEMENT SECTIONS IN ONTARIO
Bibliographic record
Abstract
In 1982, four experimental sections of rigid pavement were constructed on Highway 3, southeast of Windsor to assess the comparative performance and overall serviceability of various pavement, drainage, and shoulder designs plus 2 types of surface textures. Recent innovative developments in concrete pavement design methodology, material specification, construction techniques, and pavement drainage systems prompted Ontario's Ministry of Transportation to construct these alternative test pavements. A summary of the design and construction details, plus the performance results of an ongoing monitoring program are documented in this paper. The performance of the pavement sections is described in terms of load transfer and pavement edge deflections based on FWD testing, Pavement Condition Ratings, roughness, skid resistance, joint movement and a crack survey. Observations of noise levels, traffic volumes, and surface texture are discussed. Conclusions based on six years of performance results indicate the superior performance of the free draining base materials. In addition, some anomalous behaviour based on pavement cracking and roughness suggest additional areas of process control are warranted.

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.
