4. Conclusions

Melting snow on airport pavement with carbon fiber grille was researched in this paper. The design and construction of airport pavement is reasonable, which the carbon fiber grille is located 5 cm below the pavement surface and the interval of heating wires is 10 cm. From the limited experiments, a snow-melting input power of 200–350 W/ m2 is required according to the snowy weather condition in Beijing. The validity of the proposed method of snow-melting with carbon fiber grille has been verified with the results of field full-scale experiments.

In the process of snow-melting, most of the energy is used to melt snow and heat airport pavement, the system inherently creates a nonlinear temperature gradient within the pavement. Whether the temperature stresses are large enough to induce a thermal expansion which widens existing cracks in the pavement and accelerates corrosion of the reinforcing mesh is still a question that needs to be researched. The further researches include: the influence of the carbon fiber grille on the function of the structure and the bond between the reinforcing steel and the concrete; the field experiments of snow free all the time; the influence of the electromagnetic field on the aircraft navigation; and the application in practical engineering.
