Abstract
An energy harvesting roadway that includes a plurality of road segments and a power storage device electrically coupled to the plurality of road segments. Each of the plurality of road segments can include a surface asphalt layer, a first conductive asphalt layer located under the surface asphalt layer, a piezoelectric-based asphalt layer located between the first conductive layer and a second conductive layer located above a base asphalt layer. The piezoelectric-based asphalt layer can include a plurality of rigid piezoelectric elements and an insulating filler.
