## 1 Introduction
[PERSON] [19] used a heated pavement snow melting model experiment to examine the melting processes of uncompressed and compressed snow, and the findings revealed that melting compacted snow takes more time and energy. In terms of mechanical properties, [PERSON] [20] confirmed that internal heating cables may be employed in cold-weather concrete floor construction. By shortening the time it takes for concrete slabs to dehydrate in cold areas, this heating technique can strengthen the road and speed up the drying process. [PERSON] [21] examined the temperature stresses in thick concrete pavement panels by field experiments as well as 3D finite element models and provided a method to calculate the actual temperature stresses in concrete pavement in a computer field. [PERSON] [22] created a thermodynamic model of concrete under high-temperature action that could mimic the residual mechanical behavior of concrete at high temperatures, including stiffness, strength loss, Poisson's ratio reduction, and inelastic behavior changes. [PERSON] [23] validated the damage plasticity model's applicability by measuring the uniaxial characteristics of concrete under cyclic stress at high temperatures, providing fresh temperature-dependent calibration data for the damage plasticity model. [PERSON] [24] examined the coupling effect of high temperature and high strain rate in concrete using the finite element modeling software ABAQUS ([https://www.3 ds.com/products/simulia/abaqus/cae](https://www.3 ds.com/products/simulia/abaqus/cae) (accessed on 21 November 2023)) and a damage plastic concrete model. [PERSON] [25] investigated the damage morphology of plain concrete under high-temperature action, and the results revealed considerable variation in the damage morphology of concrete at ambient temperature. [PERSON] [26] proposed an intrinsic model to study concrete deformation under transitory temperature and pressure conditions, which incorporated both thermochemical and mechanical damage. [PERSON] [27] established a thermodynamically consistent gradient poroplastic model for high-temperature concrete and demonstrated its prediction power for various stress routes and thermal circumstances. [PERSON] [28] used Paris' rule to quantify the cumulative fatigue fracture damage of PCMrich concrete slabs subjected to cyclic hot bending stresses. [PERSON] [29] evaluated the danger of thermal fractures in concrete constructions. According to the findings of this study, pre-embedding heating wires before pouring the concrete construction can minimize temperature stress during the hydration process. The research in the aforementioned publications was all conducted at high temperatures outside the concrete pavement and did not examine the mechanical characteristics of concrete pavement with integrated carbon fiber heating wires. Therefore, there is a lack of studies on the mechanical behavior of electrically heated pavement materials. This study aimed to investigate the temperature and thermal stress distributions inside concrete pavement with embedded carbon fiber heating wires through model tests and numerical simulation. The accuracy of the numerical model is verified by comparison to model test results. The analysis reveals the maximum tensile and compressive stresses generated during the heating process and their distribution characteristics. Moreover, the relationship between the temperature gradient and thermal stress is quantified. The findings can provide a reference for the design of electrically heated concrete pavement.
