Electrical-snow melting asphalt concrete pavement used for municipal roads

Abstract

The invention relates to an electrical-snow melting asphalt concrete pavement used for municipal roads, which is characterized in that the asphalt concrete pavement comprises snow melting heating cables; heat-conducting asphalt concrete is paved above the snow melting heating cables; a thermal insulation layer is paved below the snow melting heating cables; the snow melting heating cables are connected with a controller through cold leads; and a temperature sensor is disposed in the heat-conducting asphalt concrete. The electrical-snow melting asphalt concrete pavement of the invention makes use of the principles of electrical heating and heat conduction, and realizes heating of the steel-pipe-protected heating cables by electric energy. An upper surface layer of the heat-conducting asphalt concrete is adopted; the thermal insulation layer is disposed below the cables in the pavement structure; the system output power is controlled by a control switch with three levels of high, medium and low levels; the temperature sensor is disposed for real time control of the road surface temperature during the system snow melting period. With the above concrete measures, both the system snow melting effect is guaranteed and the energy consumption is decreased to the maximum extent, and the pavement is convenient to service and maintain. The electrical-snow melting asphalt concrete pavement has the characteristics of high efficiency, low energy consumption, quick heating, environment friendliness, economy, convenient service, long service life, and the like.

Description

technical field [0001] The invention belongs to the field of road traffic, and mainly relates to an electric snow-melting asphalt concrete road surface applied to municipal roads. Background technique [0002] The normal use of urban roads is often affected by snow in winter in northern my country. On the one hand, due to the ice and snow reducing the road surface friction resistance of a normal driving car, the traction force of the car is indirectly reduced, making the speed of the vehicle lower and making it difficult to drive the vehicle; cause traffic accidents. At present, roads in northern cities are mainly cleared by spraying deicing agents (ice-melting salt, etc.) and mechanically, and the Cl in deicing agents -1 It will accelerate the corrosion of steel bars in bridge structures and the aging of road surface asphalt, which not only affects the performance of roads and bridges, but also pollutes the environment after being discharged into water. The invention uti...
