Interfacial adhesion mechanism between asphalt and aggregate with different lithology in acid–alkaline aqueous solutions
Bibliographic record
Abstract
Strong adhesion at the asphalt–aggregate interface is vital for asphalt mixtures’ mechanical properties, but water damage can erode this adhesion, causing pavement distress. This study analyzed the effect of aggregate lithology (basalt, granite, and two limestones) on the water damage resistance of asphalt interfaces in acid–alkaline solutions using the boiling method, atomic force microscopy (AFM), and zeta potential measurements. AFM-measured interaction forces aligned with Derjaguin–Landau–Verwey–Overbeek theory. Acidic conditions showed higher adhesion forces and lower repulsive forces compared to alkaline conditions. Zeta potential values and long-range forces decreased with rising pH. Adhesion order in solution was limestone A > limestone B > basalt > granite. These findings reveal how aggregate lithology influences asphalt adhesion, aiding material selection for durable pavements.

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.
