It is current interest to make good use of asphalt pavements and airport runways as environmentally friendly solar collectors for the heating and cooling of adjacent buildings as well as to keep the pavements ice-free directly. The process of extracting heat energy from asphalt pavements was investigated in this study. Water flowing through copper tubes inserted within small laboratory prepared asphalt concrete slabs was used as heat exchanger. The rise in water temperature as a result of flow through the asphalt concrete slab was used as the indicator of the efficiency of heat exchange. Thermal conductive fillers were utilized to improve the thermal conductivity of asphalt concrete and thus resulting in an improved efficiency of asphalt collector. Experimental results showed that the heat energy obtained from solar irradiation can be enhanced by means of Conductive Asphalt Concrete (CAC). The circulating water has a cooling effect on decreasing the high temperature within asphalt concrete and thus reducing its risk of permanent deformation. Focus is on mixture design to prepare an effective heat exchanger that is capable to extract a maximum heat from asphalt pavements.
