Abstract
Mixtures of small rigid sand particles D s and large soft rubber particles D r are prepared at different volume fractions and tested to investigate their small-strain and zero-lateral strain responses (D r /D s ≈ 10). Both data sets are simultaneously gathered in an oedometer cell instrumented with bender elements. Data are analyzed in the context of mixture theory and with the aid of numerical simulations. Results show that the sand skeleton controls the mixture response when the volume fraction of rubber particles is V rubber ≤ 0.3, while the rubber skeleton prevails at V rubber ≥ 0.6. The large size and incompressibility of rubber particles provides high stress-induced stiffness in the sand skeleton near the equatorial plane of rubber particles. The corresponding increase in local small-strain shear modulus G max results in earlier wave arrivals in mixtures with V rubber ≤ 0.3 than in pure sand, while the quasi-static constrained modulus is highest in pure sand. The constrained modulus and shear wave velocity are power functions of the applied effective stress in all mixtures. Results from this study (D r /D s ≈ 10) and from a previous complementary study with small rubber particles (D r /D s = 0.25) show that the development of internal fabric, particle level processes, and the associated macroscale response of sand–rubber mixtures depend on the relative size between the soft rubber chips and the stiff sand particles D r /D s and their volume fractions.

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
