Design and Construction of a Pervious Concrete Pavement in Ontario, Canada
Bibliographic record
Abstract
The Ontario Ministry of Transportation (MTO) designed and constructed its first pervious concrete pavement in 2007. The pervious concrete pavement serves as a commuter parking lot located adjacent to Highway 401 near Milton, Ontario, approximately 50 km west of Toronto. The final design consists of 240 mm of pervious concrete over 100 mm of open graded clear stone, over 200 mm of granular base material, over select subgrade material, over silty sand subgrade. Pervious concrete pavements provide many environmental benefits and are deemed a stormwater management best practice. These benefits may be offset by concerns with winter durability and the potential for clogging, especially with traditional winter maintenance. The Contractor elected to use a Bid-Well bridge deck finishing machine for placing the majority of the pervious concrete pavement. A Razorback screed (i.e. air driven steel truss) was used to construct the last section of the pavement. This paper presents the design considerations and summarizes the construction observations and lessons learned. Laboratory performance data for the pervious concrete pavement are also presented.

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.
