Evolution of meso-structural characteristics of porous asphalt mixture and its effect on heat transfer performance under progressive clogging

Key Points

• Heat transfer performance is adversely affected by progressive clogging in porous asphalt mixtures.
• Key evidence shows that increased clogging leads to reduced thermal conductivity measurements over time.
• Analysis of meso-structural characteristics shows how they evolve based on clogging levels in the asphalt.
• Findings highlight the importance of maintaining porosity to optimize heat transfer performance.
