Abstract

fetched live from OpenAlex

Rutting is considered a highly significant failure in bituminous pavements. Wheel tracking tests are widely used laboratory simulation tests to characterize the rutting resistance of bituminous mixtures. Considerable variation is observed in the accumulated rut depth at different locations along the wheel traverse and the representative rut curve obtained from different methodologies also shows significant variations. A probabilistic approach was adopted to analyze this scatter in the rut depth at a specific number of wheel passes and reliability-based rut curves were developed. Weibull and lognormal distributions are better at characterizing the scatter in the accumulated rut depths at various locations than the normal distribution. The results from the probabilistic rut data for two different binders and two different bituminous mixtures tested at six different temperatures at a specific number of wheel passes showed that different representative rut curves have different percentages of reliability. This work provides a rationale for choosing a representative rut curve from different methodologies.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
