Problems solved by technology

When the salt sprinkler is spreading salt, it is difficult to spray the salt powder evenly on the icy road surface, which leads to the remaining small pieces of ice on some road surfaces. The existence of these remaining local ice surfaces is still a threat to traffic safety. Potential safety hazard
Furthermore, since the use of salt to suppress road icing has a certain timeliness, it can usually produce the best technical effect of curbing icing for about one hour after spraying, and the above-mentioned curbing effect will gradually disappear within a few hours afterwards , in case of continuous freezing weather, in order to meet the needs of driving safety, repeated spraying is required, which consumes a lot of financial, manpower and material resources
In addition, since the spraying is usually industrial salt, it will also have a certain adverse effect on the surrounding soil after natural diffusion.

Abstract

The invention relates to a heat-preservation anti-freezing road and a construction method thereof, and belongs to the field of building materials and construction. The road is formed by sequentially laying a crushed stone layer, a cement stabilized layer, a heat insulation layer, a heating layer, an asphalt concrete layer and a heat-preservation coating layer on a leveled and cleaned pavement baselayer from bottom to top, external solar energy is used for heating, and silica aerogel is used as a substrate, so that the problem of energy consumption loss caused by the fact that heat of the heating layer is transmitted to the ground can be effectively solved, heat conduction oil adopted by the heating layer has an extremely strong absorption and conduction effect on solar energy heat release, and an iced road surface can be effectively melted. Good application prospects are realized on road ice melting in cold regions.

Description

technical field [0001] The invention relates to a thermal insulation and antifreeze road and a construction method thereof, belonging to the field of building materials and construction. Background technique [0002] In winter and early spring when the temperature is lower than 0°C, the snow may freeze on the road immediately or melt and form road icing on the road due to the drop in temperature. As long as the temperature does not rise enough to thaw the ice layer, the ice layer will remain rock-solid, which is an important culprit of traffic accidents. At present, road deicing mainly adopts mechanical and chemical methods. The mechanical method is to directly act on the road ice accumulation and compacted snow through mechanical devices. It mainly includes impact ice breaking, multi-section whip whipping deicing, roller rotating ice removal and shovel removal, etc., but ice accumulation and compacted snow are combined with the road surface. If the force of the deicing mac...
