As an important development direction of transportation in the future, the full supply of electricity is the prerequisite for smart roads to exert their intelligence. The thermoelectric pavement can convert the internal temperature difference of pavement into electricity, which is an effective way to supply electricity for smart roads. However, existing thermoelectric elements have the outstanding problem that it is difficult to balance the high efficiency and traffic load, and the cooperative working mechanism between thermoelectric elements and asphalt pavement is not yet clear. Therefore, from the perspective of major in materials for new energy and major in road engineering, this project carries out systematic research. Firstly, new thermoelectric elements with high power generation efficiency are developed through high-throughput calculation, the first-principle and molecular dynamics analysis. Then, the temperature distribution and mechanical response analysis of the new thermoelectric asphalt pavement are carried out through Finite Element Method, the layout and buried depth of new thermoelectric components are determined, and cooperative working mechanism between thermoelectric elements and asphalt pavement is proposed. Finally, a new outdoor prototype system is built to evaluate the functionality and durability of the new thermoelectric asphalt pavement, and its job suggestion in view of all weather is built. The research results will provide theoretical and technical support for the research of thermoelectric pavement, and supply green electricity for electrical infrastructure in smart road, which has remarkable theoretical and practical engineering significance.
