Abstract
A series of research works on an introduction of snow-melting equipments to airport asphalt pavements were conducted to prevent air traffic disturbance due to snow and ice. The laboratory tests show that the snow-melting equipments do not affect the deformation and dynamic stability of the asphalt concrete layers. The loading tests on the experimental pavements having snowmelting equipment show that the deflection and rutting of pavements are scarcely influenced with the type and installation depth of snow-melting equipments. Although the accumulated deformation of layers increases as the depth becomes shallow, 3-D finite element analysis shows that the stress of snow-melting equipments caused by aircraft load is sufficiently small against the strength. It is concluded from the above that the snow-melting equipments might be installed successfully to airport asphalt pavements.
