Canadian Usage and Practices for Evaluating Warm-Mix Asphalt Moisture Susceptibiliity
Bibliographic record
Abstract
Warm Mix Asphalt (WMA) technology is gaining more acceptance by transportation agencies in Canada due to the pressures from environmental agencies and environmental acts to reduce Green House Gas (GHG) emissions generated by production and placement of paving mixtures. However, WMA technology has certain functional considerations, namely moisture susceptibility, that need to be addressed in order to ensure it meets performance requirements in addition to providing environmental benefits. To identify possible gaps in the current understanding and performance of WMA, a Canada-wide survey has been prepared at the Centre for Pavement and Transportation Technology (CPATT) located at the University of Waterloo to document the Canadian state-of-the-art related to WMA technologies. This paper presents the results of this survey on the preferred practices conducted by various Canadian transportation agencies. Furthermore, these results are compared with the most recent survey of the United States Departments of Transportation (DOTs) and industry conducted as part of the National Cooperative Highway Research Program (NCHRP) project 09-49.

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.
