Analysis of a heat exchanging asphalt layer using a finite ...

In this paper, the use of a heat exchanging asphalt layer (HEAL), as a means to extract low temperature heat, is studied in detail. Such a system, which harvests heat energy by flowing water through a heat exchanger embedded in the pavement structure, could definitely have a significant thermal energy output since pavement materials absorb ...
