Melting snow on airport cement concrete pavement with carbon fibre heating wires

摘要

In this paper, the method of melting snow with carbon fibre heating wires buried in airport cementconcrete pavement is presented to avoid the adverse effects of snow-melting chemicals. The snowmelting experiment of pavement is conducted when the snow is heavy and the air temperature isfrom −4to−3°C. Electrical power is supplied to the pavement through the use of carbon fibreheating wires. It is shown that, with an input power of 300 W m~(-2), the temperature of pavementsurface can achieve an increment of 7.48°C and the 2.5 cm thick snow can be melted within 4hours, which is just for melting snow at this condition. The temperature and energy distributionalong the depth of pavement is analysed at different times. The findings indicate that the methodof melting snow on airport pavement with carbon fibre heating wires is feasible in the snowyweather condition.
