A feasibility study on cooling asphalt pavements using heat pipe water cooling method
ABSTRACT
In hot weather, asphalt roads can suffer from plastic deformation due to high temperatures, causing ruts and reducing their lifespan. Heat pipes, efficient heat transfer devices, have the potential to cool asphalt roads. This study aims to assess their performance through a thermal resistance network model and numerical simulations. Results show that using heat pipes can reduce the average temperature of AC-16 C asphalt layers by 24.5°C and AC-25 C layers by 31°C. Closer spacing and lower cooling water temperature improve cooling. These findings are crucial for optimizing heat pipe cooling systems and improving asphalt road heat dissipation, benefiting road engineering.
