Problems solved by technology

However, this method requires a lot of manpower and material resources, and the long-term use of snow melting agent will cause corrosion to the road surface and pavement structure, resulting in shortened service life of the road surface
Moreover, the snow after using deicing agent is often piled up in the green belt or farmland on both sides of the road. After the snow melts, its salt residue will cause a large number of death of green vegetation.

Embodiment 1

[0015] Embodiment 1: The thickness of the first-class road pavement surface layer is 15cm, the thickness of the base layer is 38cm, and the thickness of the subbase layer is 40cm. The cement-stabilized gravel soil is mixed with a certain amount of gravel (generally not more than 50%). The compaction degree of the subbase is 95.9, and the water content is 4.1. The compaction degree of the base is 94.9, and the water content is 4.3. A 5mm graphene heating film is laid between the surface layer and the base layer. When laying the 40cm subbase and the 38cm base, it is necessary to strictly follow the design plan. After the paving is completed, before laying the 5mm graphene heating film, the bridge deck should also be inspected, and problems such as pits and looseness on the bridge deck should be repaired in time.

[0016] When laying and laying 5mm graphene heating film, it is necessary to remove the debris on the base of the bridge deck, so that the diameter of dust, particles ...

Embodiment 2

[0018] Embodiment 2: the fine-grained asphalt concrete thickness of the secondary road is 4cm, the Chinese asphalt concrete thickness is 6cm, the cement concrete crushed stone thickness is 20cm, and the graded crushed stone thickness is 20cm, and the 5mm graphene film is laid on the cement concrete crushed stone. between stone and Chinese asphalt concrete. The porosity of asphalt concrete is 68%; the asphalt content is 5.5%, and the porosity after compaction is required to be 5%. According to the porosity of the laboratory Marshall test piece of 4%, the on-site compaction degree should be controlled between 98% . The 20cm graded crushed stone and 20cm cement concrete crushed stone are paved according to the design plan.

[0019] When placing and laying 5mm graphene film, the sundries on the pavement base should be removed, so that the diameter of dust, sharp protrusions and large particles should not exceed 5mm. A 5mm graphene film has a length of 15m and a width of 10m. Wh...

Abstract

The invention belongs to a road surface construction technology of road engineering in the field of highway engineering, and relates to a road surface paving construction method using the heating principle of a graphene heating film. According to the road surface paving construction method disclosed by the patent, the heat-conduction heating characteristics of graphene are utilized, and the road surface paving construction method has the advantages of avoiding a road surface from being iced, enabling people to travel conveniently, guaranteeing safe travelling of people and the like. The road surface paving construction method disclosed by the patent comprises the following steps of: step I, laying a soil base to a road surface base course in sequence; step II, laying a graphene heating film; and step III, measuring the temperature with an infrared temperature measuring device. Through the adoption of the road surface paving construction method, a road surface can be heated in the winter, so that the temperature of the road surface is maintained to be zero or above, icing of the road surface is avoided, the phenomenon of vehicle slip is avoided, daily travel of people is convenient, and the travel safety of people is guaranteed. The strong heat-conduction heating characteristics of the graphene heating film are utilized, so that the problems of short service life of the road surface and death of massive green vegetation caused by excessive use of snow melting agents are solved, investment of human and material resources is reduced and energy is saved.

Description

technical field [0001] The patent of the present invention belongs to a road surface pavement construction method using the principle of graphene heating film heating in the road construction technology of road engineering in the field of road engineering. Background technique [0002] In recent years, extreme weather has occurred in our country from time to time, such as the occurrence of icy roads in winter, which not only brings great inconvenience to people's travel, but also poses a threat to people's travel safety. At present, the commonly used snow removal method in our country is to sprinkle deicing agent or fine sand to increase the melting speed of road snow. However, this method requires a lot of manpower and material resources, and the long-term use of snow melting agent will corrode the road surface and the structure of the road surface, resulting in shortened service life of the road surface. And the snow after using the deicing agent is often piled up in the ...
