Design and Instrumentation Plan for a Long Life Pavement in Ontario
Bibliographic record
Abstract
Transportation agencies are under increased pressure to extend pavement service life and reduce delays to the travelling public. These demands have resulted in the development of perpetual pavements, also referred to as long life pavements. A perpetual pavement is a flexible pavement designed from the bottom up to resist structural failure, minimize cracking and rutting, and last for 50 years or more with only periodic renewal. In 2006, the Ministry of Transportation Ontario (MTO) begins construction of its first perpetual pavements, with extension of Hwy 406, near Thorold and reconstruction of Highway 402, near Sarnia, Ontario. The Hwy 402 project will be constructed in three sections: a 4 km trial section of perpetual pavement with rich bottom mix as the lower binder; a 4 km trial section of perpetual pavement with Superpave 25 mm as the lower binder; and a control section of conventional flexible pavement. The perpetual pavement trials and control section will be instrumented, to better understand how the different pavement structures react and perform under various traffic loadings and environmental conditions. This paper describes the pavement design for each trial section on Hwy 402, the requirements for the rich bottom mix, and the instrumentation plan. A long-term monitoring program will also involve annual Falling Weight Deflectometer testing, roughness and rutting measurement, and manual distress surveys.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
