Description

Planar heating element for road {PLANAR HEATING ELEMENT FOR ROAD}

The present invention relates to a planar heating element for a road, and more particularly, to a planar heating element for a road that is buried to prevent freezing of the road and thaws the road by heat.

The road is paved using asphalt concrete (hereinafter referred to as asphalt concrete) or cement concrete.

Ascon, which is used as most of these road pavement materials, is a mixture of asphalt, coarse aggregate (gravel), fine aggregate (sand), or pavement filling material (filler, stone powder) at room temperature or at room temperature. are divided into several categories according to

In general, when snow falls on the road and freezes in winter, vehicle accidents and pedestrian safety accidents may occur. Therefore, it is necessary to prevent the road from freezing by quickly melting the snow accumulated on the road.

In particular, in the case of a bridge, the geothermal heat does not rise compared to the general land, so it is easier to freeze than a general road under the same conditions.

Tunnel entrances and exits where there is always shade are also habitually frozen areas.

In addition, the intersection of the expressway has a steep slope, which may lead to a serious accident when the road surface is frozen.

Therefore, it is necessary to make an effort to prevent freezing at all times in this section.

Conventionally, a slipping accident was prevented by mainly spraying chemicals such as calcium chloride to melt snow, or by spraying sand on the road.

However, in the case of sudden heavy snowfall, since calcium chloride or sand must be directly sprayed on the road, rapid snowmelting work is impossible, and a lot of time, personnel, and equipment are required.

In addition, calcium chloride may corrode vehicles or facilities after spraying, and it is difficult to expect a fast snow melting effect depending on the amount of snowfall.
