Abstract Combining compression molding and pouring molding, flat decing module of thermoelectric cement-based composite material was prepared, which overcame the defect of breaking due to thermal stress, expands the heat transfer surface of the composite material and strengthens the thermoelectric core. The temperature changes and voltage changes on both sides of a single module and flat cement-based composite mate-rials at room temperature were monitored through a test device composed of a constant current power supply and a data recorder. The variation law of the temperature on both sides of the cement-based composite material with the energized current and the energized time was studied, and the average temperature difference between the two sides of the sample and the Joule heat generated within the rated time were calculated. As the energizing current gradually increased, the heating rate on both sides gradually increased, and the temperature difference also gradually increased. As the electric field strength increases, the migration of electron carriers became more apparent in cement-based composite materials (N-type semiconductors), that enhanced the Peltier effect. Due to the heat exchanged between the cement-based composite material and the environment, there was an upper limit to its surface temperature. The ice-melting experiment was simulated in the refrigerator. When the energized currents were 1.0 A, 2.0 A, and 3.0 A, the final temperature of ice melting was different, but the measured ice melting time was basically consis-tent with the predicted value. When the energizing current was 3 A, the ice melting time on both sides of the positive and negative electrodes differed by 23 min. Therefore, the study of “temperature difference pavement” had certain guiding significance for the development of pavement ice melting technology.
