摘要：
A two-dimensional heat transfer model was established using the finite element numerical simulation approach to investigate the heat transfer characteristics and its influence law of electric heating snow-melting asphalt pavement. The impact of heating system design parameters（layout spacing，embedding depth，and input power）and environmental parameters（wind speed，ambient temperature）on surface temperature distribution and heating rate of the pavement was investigated，and the accuracy and effectiveness of the model are verified by the measured data of the test section. The results revealed that the two-dimensional heat transfermodel can predict road surface temperature of electrothermal snowmelt asphalt pavement well in an accurate level，with an average maximum absolute error of 1.1 °C，an average accuracy of 88.1%，and a maximum accuracy of 96.6%. Among all the factors，layout spacing is the most important factor affecting the temperature uniformity of the road surface，followed by embedding depth. Input power and environmental factors mainly affect the temperature rising rate and the maximum temperature of electrothermal snowmelt asphalt pavement. © 2023 Editorial Board of Jilin University.
