Overview

This research examines temperature variations in asphalt pavements, revealing significant differences between heterogeneous and homogeneous models.

Key Points

  • The three-dimensional heterogeneous heat-transfer model accurately represents temperature variations in asphalt pavements, enhancing understanding.
  • Experimental validation shows that the new model significantly outperforms the homogeneous model with R² values greater than 0.95.
  • Controlled heating experiments confirm the reliability of the thermophysical parameters in the heterogeneous model.
  • This study provides critical insights for improving asphalt-pavement maintenance and hot-recycling technologies.
