Understanding the Molecular Surface Charges of Asphalt or Clay Particles and Application in the Transportation and Oil Sands Industries
Bibliographic record
Abstract
Abstract Asphalt binder is a mixture of many different types of molecules. At the molecular level, one can visualize the asphalt binder as a colloidal system with asphaltene molecules dispersed in oil with naphthene and polar aromatics. The functional groups of the asphaltene molecules are essential in keeping them dispersed as colloids. These polar functional groups include alcohol, amine, carboxylic, and phenolic groups. The polarity of asphalt molecules are very important in allowing them to adhere to the inorganic aggregates, which also bear charges at the surface. The application of this understanding to the aging of paving asphalt, asphalt modification, the Superpave direct tension test, aggregate specific gravity determination, ash as modifiers in asphalt, low-volume road chemical stabilization, and the oil sands industry are discussed.

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.
