Abstract
This paper presents an investigation of the dynamic modulus, fatigue properties, and static creep of ten different Superpave mixes used in Costa Rica. The mechanistic properties were compared with empirical properties and also with equivalent Marshall Mix designs. The effect of the volumetric properties on the mechanistic and empirical properties was investigated. It was found that resilient modulus has a high correlation with Indirect Tensile strength yet it is not a good estimator for dynamic modulus. Effective binder content was found to correlate with the fatigue resistance. Asphalt Pavement Analyser (APA) results are highly influenced by the air voids of the specimens, whereas the benefits of using gap-graded gradations (e.g., SMA) is not reflected by the APA results. The paper shows that the tensile strength ratio (AASHTO T183 test) is highly sensitive to gradation and it fails to quantify moisture effects.

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 it
