Pavement maintenance device and maintenance method

Abstract

The invention relates to the field of road surface maintenance and particularly relates to a road surface maintenance device and a maintenance method, and solves problems that when slurry seal is carried out on a wide road surface, repeated paving is often needed on the same road section, a road surface is completely covered, and maintenance efficiency of the road surface and the traffic blocking time are affected. The device comprises a vehicle body, wherein a plurality of split charging hoppers used for containing thin slurry raw materials are arranged in the vehicle body, a mixing hopper used for mixing the thin slurry raw materials is arranged at the tail end of the vehicle body, the split charging hoppers are all communicated with the mixing hopper, the mixing hopper is connected with a plurality of spraying heads used for spraying thin slurry, and a slicking assembly is arranged behind the spraying heads; the slicking assembly comprises a telescopic slicking plate and a plurality of flattening plates used for flattening the slicking plate. The device has effects of reducing the slurry paving frequency of the same road section and improving efficiency of slurry sealing of the road surface.

Description

technical field [0001] The present application relates to the field of road maintenance, in particular to a road maintenance device and maintenance method. Background technique [0002] Asphalt pavement is affected by wheel rolling and climate change during use, and is often weathered and worn, resulting in cracking and subsidence of the pavement, which is not conducive to the normal long-term use of the pavement. In order to ensure the quality of the pavement and prolong the service life of the pavement , Reduce the frequency of overhaul or even renovation of the road surface, and preventive maintenance of the road surface is required from time to time. [0003] When using the slurry sealing technology to maintain the road surface, it is necessary to mix various raw materials of the slurry in proportion and spread them on the road surface to evenly level the slurry. After the slurry is demulsified and solidified, the road surface and the slurry will stick together The comb...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that when slurry sealing is performed on a wider road surface, it is often necessary to carry out multiple reciprocating pavements on the same road section to completely cover the road surface, which will improve the maintenance efficiency of the road surface and traffic congestion. defects of time
