Abstract

The invention relates to a fog sealing layer material, a preparation method and application. The material is prepared from, by mass, 80-120 parts of emulsified asphalt, 2-5 parts of carbon nanotube dispersion liquid, 5-10 parts of a penetrating agent, 150-250 parts of silicon carbide and 30-60 parts of ferroferric oxide. The fog sealing layer material has the repairability, when microcracks existon a fog sealing layer, a second fog sealing layer and other maintenance overlay layers are not needed, and the fog sealing layer material can be repaired through microwaving treatment; the fog sealing layer material is compounded by carbon nanotubes, the silicon carbide, the ferroferric oxide and other materials, the thermal conductivity and microwave conversion efficiency of the material can besignificantly improved, so that under the microwave effect, the efficiency of the material is higher, and it is achieved that in the same melting state, microwave energy consumption can be reduced by10-15%; the adopted material makes the fog sealing layer achieve good thermal conductivity, good microwave conversion efficiency and good pavement performance, and the carbon nanotubes can improve theperformance of an asphalt material; the silicon carbide has good abrasive resistance performance, and the abrasive resistance performance of the fog sealing layer is further improved.

Description

technical field [0001] The invention relates to a fog sealing layer material, a preparation method and an application, and belongs to the field of road traffic materials. Background technique [0002] Fog seal is a new type of preventive maintenance technology for asphalt pavement. Special equipment is used to evenly spread oil-type mist seal materials and sand materials with good permeability on the asphalt pavement. The fog seal material can fill tiny cracks and surface voids, play a role in waterproofing and inhibit loosening, and prevent further aging of pavement materials. Sand materials can increase the roughness of the road surface, improve the friction coefficient of the road surface, and ensure driving safety. This process can improve the anti-skid performance of the pavement, avoid water damage, achieve the purpose of protecting the pavement structure and prolonging the service life of the pavement. It is an economical and effective preventive maintenance measure....
