Embodiment 1
[0073] In this example, the SMA asphalt pavement of the Linxiang-Changsha Expressway is taken as the research object. The total thickness of the surface layer is 180mm, which is paved by 50mm SMA-16, 60mmAC-20 and 70mmAC-25; the thickness of the base layer is 580mm, It is paved with 380mm cement stabilized gravel and 200mm lime soil.
[0074] (1) Carry out road temperature test and collect meteorological parameters such as hourly average temperature, hourly solar radiation intensity, daily maximum temperature, daily minimum temperature, and daily solar radiation intensity peak value on Linchang Expressway, and establish road surface temperature field analysis through regression analysis According to the formula, it can be concluded that the place where the high temperature end of the embedded thermoelectric device is laid at a distance of 10-20mm from the road surface in summer, and the corresponding temperature T at this time H It is 59~63℃. At the same time, further conside...

Abstract
The invention discloses a design method of an embedded thermoelectric device for road and an embedded thermoelectric power generation pavement thereof, the structure layer of the road embedded thermoelectric device design method sequentially comprises a surface layer, a base layer and a soil base from top to bottom, a plurality of embedded thermoelectric devices connected in series are arranged inthe surface layer, and the embedded thermoelectric devices are connected with a storage battery through wires. The method aims at different types of pavements. According to the pavement working environment and the road material modulus; by designing the composition and geometric structure of the heterogeneous material at the same time and cooperatively regulating and controlling the power generation efficiency and modulus of the thermoelectric device, the thermoelectric device matches roads to obtain the high-power-generation-efficiency thermoelectric device suitable for different types of road surfaces, and then the thermoelectric device is used for the power generation road surface to obtain the embedded thermoelectric power generation road surface with high power generation efficiencyand excellent road matching performance.
Description
technical field [0001] The invention relates to a design method of an embedded thermoelectric device for roads and an embedded thermoelectric generating circuit surface, belonging to the technical field of generating circuit surfaces. Background technique [0002] In order to enable the entire road network to exert its intelligent capabilities, it is necessary to continuously supply power to smart devices such as 5G stations, signal lights, street lights, monitoring, and sensors along the road. However, there are still some "power blank areas" in my country's road network that are not powered on or have unstable power supply. Therefore, the development of new technologies for power supply of the whole road network has become the key to the continuous development of smart roads. In fact, roads also have the potential to generate electricity while undertaking transportation functions. For example, in summer, the local temperature of the asphalt pavement can be as high as 70°...
