Abstract

fetched live from OpenAlex

Research was undertaken using an innovative three-dimensional (3D) laser scanning tool to
\nstudy the shape and texture characteristics of road aggregate particles. Aggregate materials
\nused for road construction, including G1 crushed rocks of different geological origins, recycled
\naggregate and alluvial gravel (not used as aggregate) were used for this study. Representative
\nsamples were scanned using the laser system to collect 3D aggregate data for analyses and,
\nsubsequently, develop comparative models. The objective was to arrange the aggregate
\nparticles in a sequence based on their surface texture. Two models were proposed and key
\naspects evaluated against each other. Ultimately, one model was selected that may be improved
\nand used for further research. The study found that, while it is possible to use the 3D aggregate
\nscan data to produce comparative models, distinguishing between particle shape and texture
\nproved a daunting task. It was also concluded that particle elongation must be considered as a
\nmajor influencing factor.

Teacher imitation

Not 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.
