Active melting of ice and snow has gradually become an important method to solve the problem of road ice and snow. The preparation method of conductive rubber composites is produced in this paper. The snow melting effect was determined through outdoor experiments. Moreover, the corresponding finite element model was constructed. The active ice and snow melting system was used for engineering and the threshold of intelligent sensing system was determined. The results show that conductive rubber can melt 20 mm snow on the road in 3.17 h at 14 V and -8 ℃, which can realize rapid snow melting at low voltage. The outdoor test verifies the accuracy of the finite element model. The sensing system indicates that the intelligent sensing active ice and snow removal system can remove road ice and snow in time.
