Abstract

fetched live from OpenAlex

An improved laboratory test procedure for measuring thermal conductivity of asphalt concrete (AC) pavement is proposed. In this preliminary work, a simple device for thermal diffusivity of AC is developed and the corresponding thermophysical properties are measured. The measurement results indicate that the thermal conductivity and thermal diffusivity of AC are functions of compaction degree, degree of moisture saturation, and temperature. From the estimated thermal conductivity and the measured thermal diffusivity, the transient temperature response to changes in environmental conditions of an AC pavement is analyzed numerically with an incremental recursive method by applying the energy balance principle and the Fourier heat transfer equation. The analysis results show that an AC pavement undergoes diurnal temperature cycles whose amplitude decreases with depth and changes sharply at the pavement surface. In addition, with the changing frequency of the temperature, thawing and refreezing effects of the AC pavement increase progressively from January to March in New Brunswick, Canada.

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.
