Asphalt concrete pavement utilizing self-generation of direct piezoelectric effect

Abstract

The invention discloses an asphalt concrete pavement utilizing self-generation of direct piezoelectric effect. The invention provides asphalt concrete capable of burying and laying a piezoelectric self-generation unit by selection of the raw materials and the design of the mix proportion, and ensures that the road use performance of the asphalt concrete can meet the technical requirements of asphalt, and works out the thickness of a structural layer of the asphalt concrete pavement through simulation. The method comprises the following steps: burying and laying at least one piezoelectric self-generation unit in the structural layer of the asphalt concrete pavement, transforming the mechanical energy generated under the vibration or the extrusion of outside vehicles into electric energy through the piezoelectric self-generation unit and providing the electric energy for an energy collection and illumination device. The invention makes full use of the mechanical energy generated when the automobiles run on the pavement, transforms the mechanical energy into clean electric energy without pollution for roadway illumination, thereby greatly relieving the energy scarcity situation in our country and reducing the emission of harmful gas, even can be a breach for whole energy conservation work in our country, is a novel clean and environment-friendly energy saving mode and has obvious economic and society benefits.

Description

technical field [0001] The invention relates to an intelligent traffic system, in particular to an asphalt concrete pavement that utilizes the positive piezoelectric effect to self-generate electricity. Background technique [0002] The global energy shortage and climate change have become a major concern of the international community, and energy conservation and emission reduction have become the common responsibility of the international community. As the largest developing country in the world, my country is increasingly becoming the object of global attention. By the end of 2008, the installed capacity of power generation equipment in my country had reached 792.53 million kilowatts. Among them, thermal power is 601.32 million kilowatts, accounting for about 75.87% of the total capacity. It can be seen that thermal power occupies a considerable proportion in my country's electric power structure. Such a power structure has led to relatively large energy consumption and...

Problems solved by technology

Although lighting power consumption only accounts for 15% to 20% of the country's total power consumption, and the proportion of road lighting is even smaller, but from the perspective of energy-saving technology promotion, it may become a breakthrough in the entire energy-saving work.
