Abstract

The invention, which belongs to the technical field of pavement snow melting and ice melting, discloses a pavement paving structure for melting snow and ice and a use method thereof. The structure comprises a heat insulation layer, a conductive bonding layer, a waterproof bonding heat conduction layer and a wearing layer which are sequentially arranged from bottom to top. The heat insulation layeris arranged on the lower portion of the conductive bonding layer, so that the downward transmission of heat generated by the conductive bonding layer is reduced effectively and the heat losses are reduced; with the waterproof bonding heat conduction layer, a waterproof layer is arranged to prevent electric leakage caused by water entrance on the premise that heat conduction is guaranteed; the conductive electrode has a good conductive effect, and snow melting and deicing of the road surface can be effectively guaranteed. The snow and ice melting structure has the high applicability; the snowmelting and deicing of road surfaces in multiple occasions are realized in time under ice and snow weather in winter; the green and environment-friendly effects are realized; the road smoothness and driving safety are guaranteed, and low-temperature cracking of asphalt road surfaces can be effectively relieved.

Description

technical field [0001] The invention belongs to the technical field of snow melting and ice melting on road surfaces, and relates to a pavement pavement structure for melting snow and ice and a use method thereof. Background technique [0002] The snow and ice on the road surface and bridge area in winter will seriously reduce the anti-skid ability of the road surface and seriously affect road traffic safety. Therefore, how to remove ice and snow from the road surface in a timely and efficient manner is of great significance to ensure road traffic safety and traffic capacity in winter. Traditional methods of removing ice and snow from road surfaces, such as manual cleaning, mechanical removal, and deicing salt, have hysteresis, affect road traffic capacity, affect road performance, and bring environmental problems; represented by embedded heating cables, conductive grids, and conductive asphalt concrete The environmentally friendly and sustainable active electrothermal ice a...
