Abstract
This paper discusses the effects of widely used waste engine oil (WEO) residue on asphalt binder properties. Five SHRP Materials Reference Library binders and one commercial material from Ontario, Canada, were modified with 15% WEO. Materials were aged according to a standard rolling thin film oven protocol followed by 20 and 40 h of pressure aging vessel (PAV). Binder quality was determined according to AASHTO specification M 320 as well as dynamic shear characterization. Durability was assessed after additional conditioning at high temperature in the PAV and at low temperature in the bending beam rheometer. All but one of the WEO-modified materials transitioned to a gel-type state more readily upon chemical and physical conditioning; this result explains the poor thermal cracking performance seen for such binders on Ontario roads.

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
