The cutting-edge technology known as asphalt solar collectors (ASCs), commonly referred to as solar asphalt or solar pavement, is an example of one of the applications that makes use of solar energy. Specifically, these systems combine conventional asphalt surfaces with solar energy harvesting capabilities.
Asphalt pavements cover a high percentage of urban surface areas and store huge thermal energy due to high solar radiation. The thermoelectric effect can convert thermal energy into electric energy if there exist thermal gradients.
Due to exposure to vehicle loading and solar radiation, asphalt pavements store a huge amount of energy. Therefore, many different techniques have been developed to harvest energy from asphalt pavements, including thermoelectric, geothermal, piezoelectric and electromagnetic, energy harvesting.
Among all the energy sources which can be collected from asphalt pavements (thermal energy, mechanical energy and wind energy), thermal energy stands out because the pavement temperature can be reduced when generating thermal energy.
