Half and Half: One Year Later, A Mat with 50-Percent RAP Looks Really Good
Bibliographic record
Abstract
This article describes how a stretch of asphalt in Canada that was laid down in September 2009 is beginning to reveal its secrets. The initial tests on the road included the examination of a section which used 50-percent Reclaimed Asphalt Pavement (RAP) provided by the old road that it replaced. The first results are very positive and that’s good news to the proponents of using higher percentages of RAP, a process that had environmental (fewer emissions) and budgeting (lower cost) pluses for road construction. The Asphalt Research Consortium (ARC) met with Manitoba Infrastructure and Transportation (MIT) in March of 2009 to discuss research that is being conducted by the ARC and the desire of MIT to incorporate “green” technologies into its asphalt paving construction. The ARC was working on a five-year research project funded by the Federal Highway Administration (FHWA) with significant emphasis on “green” technologies like higher levels of RAP, warm-mix technologies, and cold-mix technologies.

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.
