Abstract
Different techniques have been developed for modifying asphalt cement (AC) to improve its high-temperature characteristics. Among these methods, chemical modification using polyphosphoric acid (PPA) has gained popularity in recent years, partly because it is an economical way of modifying AC. The potential problems associated with the use of such a method, however, may offset the benefits it offers. The Ontario Ministry of Transport (MTO) has developed a six-step plan to help the ministry address these concerns with the goal of balancing the benefits with the risks. The plan, which is discussed in this paper, consists of the following six steps: (1) conduct environmental scan; (2) identify issues, concerns, and benefits; (3) consult with industry; (4) develop a risk management plan; (5) specify revision and implementation; and (6) monitor and review options.

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 it
