Pavement maintenance device and use method thereof

Abstract

The invention relates to a pavement maintenance device and a use method thereof. The pavement maintenance device comprises a vehicle body, a heating tank is installed at the top of the vehicle body, a stirring mechanism is installed on the heating tank, and a first spray head assembly, a jet head assembly and a second spray head assembly are sequentially arranged at the bottom of the vehicle body from the vehicle head to the vehicle tail. The heating tank is provided with a first high-pressure pump and a second high-pressure pump, a first feeding pipe is installed between the first high-pressure pump and the first spray head assembly, a second feeding pipe is installed between the second high-pressure pump and the second spray head assembly, an air compressor is fixedly installed at the top of the vehicle body and connected with an air feeding pipe, and the end, away from the air compressor, of the air supply pipe is connected with the jet head assembly. The pavement maintenance device has the effect of improving the curing effect of a curing agent.

Description

technical field [0001] The present application relates to the field of sanitation equipment, in particular to a road surface maintenance device and its usage method. Background technique [0002] Due to the influence of environment, climate, traffic load and many other factors, the asphalt pavement will have asphalt elasticity decline, aggregate exposure, slight cracks and other phenomena. It seems to be a good road on the surface, but it has actually entered a "sub-healthy" state. Therefore, the asphalt pavement needs preventive maintenance at regular intervals, so as to delay the further damage of the asphalt pavement. [0003] When the asphalt pavement is maintained, the curing agent is generally applied to the asphalt pavement manually, and the curing agent generally uses an asphalt pavement curing agent. After that, the curing agent relies on its own fluidity to penetrate into the cracks and holes of the asphalt road, thereby infiltrating, activating, repairing and res...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that there is air inside the holes and gaps of the asphalt pavement. After the curing agent is applied to the asphalt pavement, the air in the holes and gaps of the asphalt pavement is difficult to discharge, and then the curing agent flows into the holes and gaps. Will be hindered by the air and the flow rate will be slow, or even unable to flow

At the same time, the temperature of the curing agent will gradually drop after being applied, so that the curing agent will gradually solidify and the fluidity of the curing agent will gradually decrease.

If the curing agent flows slowly, the curing agent will gradually solidify, which will cause the curing agent to penetrate into the asphalt pavement to a small depth, thus affecting the curing effect of the curing agent
