Study on performance deterioration of asphalt and asphalt mixtures containing Mafilon under internal salt freeze–thaw cycles
Bibliographic record
Abstract
The purpose of this work is to determine the implications of internal salt freeze–thaw cycles (F–TCs) on performance deterioration to asphalt and asphalt mixtures containing Mafilon (MFL). The deterioration to different numbers of F–TCs and different MFL contents on asphalt properties and mechanism were investigated by physical properties tests and microcosmic tests. Then the damages of road performance indexes of asphalt mixtures containing different MFL contents were studied by road performance tests. The experimental results show that asphalt containing MFL after F–TCs has a remarkable decline in ductility and penetration, while growth in softening point. Internal salt F–TCs are most damaging to the cryogenic properties of asphalt. Chemical reactions and salt aging effects occur in salt F–TCs, raising the glass transition temperature of asphalt. Road performance tests indicate the deterioration of internal salt F–TCs to high temperature stability and water stability is the most pronounced, with 29.18% and 21.78% reduction, respectively.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
