Antifreeze road and its construction method for preventing road surface from freezing

Abstract

The invention discloses an anti-freezing road capable of preventing a road surface from being frozen and a construction method of the anti-freezing road. The road surface is firm and durable, high in safety coefficient and low in maintenance cost. A heating layer is additionally arranged on a surface layer and a base layer of a common road, so that the road surface is heated before or when rain and snow fall in winter; and a condition that the rice and snow are frozen on the road surface due to a very low air temperature so that the traffic is influenced and the potential safety hazards are caused is effectively avoided; and a lot of manpower and material resources for removing ice and snow are saved. Meanwhile, heating films are laid in the middle of cement concrete, so that on one hand, the quantity of the heating films is reduced; and on the other hand, a waterproof layer can be stuck with the cement concrete of a heating layer very well, so that a condition that upper-layer and lower-layer separation of the road is caused due to the heating films so that the service life of the anti-freezing road is influenced is avoided.

Description

technical field [0001] The invention relates to the field of road construction, in particular to an antifreeze road and a construction method for preventing road surface from freezing. Background technique [0002] In northern China, especially in the Northeast and northern Inner Mongolia, roads often freeze. In southern China, snowfall is generally "wet snow", which often belongs to mixed water at 0-4°C, and it will become ice-water paste when it hits the ground. When the temperature drops at night, it will solidify into large pieces of ice. As long as the local winter If the minimum temperature is below 0°C, there is a possibility of road icing. As long as the temperature does not rise enough to thaw the ice, it will remain rock solid. Generally speaking, in the twelfth lunar month of winter, when there is a large-scale strong cold air activity that causes the temperature to drop (called a cold wave in meteorology), if it is accompanied by rain and snow, road icing is mos...

Problems solved by technology

When the road is icy, it will seriously affect the traffic of vehicles and pedestrians, and even cause various traffic accidents, causing heavy property losses

[0003] At present, the commonly used methods of snow melting and deicing on the road mainly include mechanical or manual shoveling, sprinkling industrial salt or snow melting agent on the road, which is not efficient, the effect is not ideal, and consumes a lot of manpower and material resources. Therefore, the construction of new Anti-freezing roads that prevent roads from freezing will definitely be the future development trend, and it is a good thing for the country and the people
