Abstract

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.

Description

technical field

[0001] The invention belongs to the field of asphalt concrete, and in particular relates to a piezoelectric asphalt concrete and a power generation surface structure thereof. Background technique

[0002] With the rapid economic development, my country's road engineering construction has been gradually improved. By the end of 2012, the total mileage of my country's highways had reached 4.23 million kilometers. From open traffic to life summary, the pavement will bear hundreds of thousands or even millions of vehicle loads. Considerable kinetic energy and strain energy are obtained from the work of gravity. If the kinetic energy and strain energy generated are converted into electrical energy, huge economic and social benefits will be brought.

[0003] There are already some power generation road surfaces in China, and their research results are mainly divided into the following three categories: In 2008, an Israeli company developed a road surface energy har...
