Mechanical properties of reclaimed asphalt pavement — natural aggregate blends for granular base
Bibliographic record
Abstract
An experimental study investigated the California bearing ratio (CBR), shear strength, stiffness, and cyclic creep properties of crushed, reclaimed asphalt concrete pavement (RAP) — natural aggregate blends for granular base and subbase. The CBR was found to depend on the properties of the constituent materials and the compactive effort used to prepare the specimens. It was concluded that the CBR test may not be appropriate for evaluating the suitability of blended material for granular base construction. Based on the triaxial tests, it was observed that the addition of RAP to natural aggregate (Ontario Granular A) reduces the shear strength slightly and tends to increase the accumulated strain (deformation) that develops due to repetitive loading. The influence of RAP on the mechanical properties, including ‘elastic’ modulus, was sensitive to specimen preparation and preconditioning. For certain combinations of RAP and Granular A, the mechanical properties were similar to those of Granular A. The key to a stable blend was found to be compactive effort.

How this classification was reachedexpand
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.
