Abstract
AbstractAbstractThis study evaluated the effect of soil suction on resilient modulus of undisturbed subgrade soil specimens collected from a section located on I-40 in Canadian County, Oklahoma. A total of 18 undisturbed specimens were tested for resilient modulus (<i>M<sub>R</sub></i>) and soil suction. AASHTO 2002 Design guide <i>M<sub>R</sub></i> predictive model was used and evaluated for its reliability in predicting <i>M<sub>R</sub></i> values. Findings from <i>M<sub>R</sub></i> and soil suction tests showed that <i>M<sub>R</sub></i> increased as total and matric suctions increased. The variation of <i>M<sub>R</sub></i> with both suctions revealed the same trends. Additionally, an existing <i>M<sub>R</sub></i>-stress-suction model was modified to evaluate the variation of <i>M<sub>R</sub></i> with suction and stresses. The modified model was a reliable predictor of <i>M<sub>R</sub></i> values of unsaturated subgrade soils.Keywords: Resilient modulussoil suctionpavementssubgrade soil

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
