Pavement deicing or snow-melting system and construction method thereof

A pavement deicing or snow-melting system, comprising:

• a water-permeable pavement;
• a drainage device;
• a heating device;
• and
• an ultrasonic drainage promotion device comprising:
• ultrasonic transducers configured to convert electric energy into ultrasonic wave;
• a component for centralization, orientation and amplification of the ultrasonic wave;
• fixation bolts;
• and
• a solid wood fixation board;
• wherein the water-permeable pavement comprises, successively from the top down, a water-permeable asphalt concrete coating, a porous cement stabilized macadam layer, a reflecting layer, a waterproof layer, a semi-rigid base and a semi-rigid cushion;
• the ultrasonic drainage promotion device is arranged on a bottom of the porous cement stabilized macadam layer;
• the drainage device comprises a drainage ditch and a sheet cover;
• a water inlet is formed on the drainage ditch;
• a lower edge of the drainage ditch is not lower than the waterproof layer;
• curbs are arranged on edges of the water-permeable asphalt concrete coating and the porous cement stabilized macadam layer;
• and
• the heating device is arranged between the water-permeable asphalt concrete coating and the porous cement stabilized macadam layer.
