The traditional pavement surface collector power generation methods only consider the temperature factor. In order to optimize the adaptability requirements of traditional road surface heat collecting system for different power consumption electronic instruments, the rutting test is used to study the output efficiency of the heat collecting system under the pressure of the vehicle, and the temperature field distribution inside the asphalt pavement is studied by finite element analysis. The experimental results show that compared with the traditional pavement collecting system methods, the output efficiency of the rutting specimen under the action of 70~80 ℃ is 2.8 times that of static, and the total amount of rutting specimens per unit area collected within 4.5 hours. The energy is 45.46 kJ, which is 6~7 times that of the traditional experimental method. It can be seen that the road surface heat collection experiment needs to consider the road surface with different traffic flow and ambient temperature, and the output energy can meet the electronic measurement equipment with different power consumption requirements.
