The invention provides a piezoelectric asphalt concrete, which is composed of the following raw materials in parts by weight: 83 to 90 parts of aggregate, 4 to 6 parts of mineral powder, 2 to 4 parts of piezoelectric material, 1 to 2 parts of conductive material, and 3 to 5 parts of asphalt, wherein the total raw material part number is 100. The invention also provides two power generation pavement structures based on the piezoelectric asphalt concrete. The two power generation pavement structures utilize cooperation between the piezoelectric asphalt concrete and rod-shaped electrode or metal net electrode to achieve the electric energy collection. The piezoelectric asphalt concrete has a good economic property, and is suitable for being widely promoted and applied.
