Municipal road asphalt concrete pavement maintenance structure and construction method thereof

Abstract

The invention discloses a municipal road asphalt concrete pavement maintenance structure. The municipal road asphalt concrete pavement maintenance structure comprises a trolley used for moving, a cleaning device arranged on the trolley and used for cleaning dust and impurities of a slot seam, a melting kettle used for heating and stirring the asphalt and a leveling device used for flattening and compacting the asphalt; the cleaning device comprises a dust collection assembly used for removing dust and removing impurities of the slot seam, a scrubbing assembly used for scrubbing the slot seam and a drying component used for drying the slot seam which are sequentially distributed along the X-axis direction; the melting kettle comprises a kettle body used for temporarily storing the asphalt, a kettle cover and a stirring assembly used for stirring the asphalt; and the leveling device comprises a plurality of flattening assemblies used for flattening the asphalt in the slot seam and a compaction assembly used for compacting the asphalt in the slot seam. The municipal road asphalt concrete pavement maintenance structure is specially designed for a highway pouring seam, and is reasonable in structure, good in pouring effect and high in repairing quality.

Description

technical field [0001] The invention relates to the technical field of highway maintenance, in particular to an asphalt concrete pavement maintenance structure for municipal roads. Background technique [0002] As the country attaches great importance to road construction, asphalt concrete pavement is also widely used in the field of road engineering. Cracking of asphalt pavement is one of the main diseases encountered in the use of asphalt pavement. The main reasons for asphalt pavement cracking are as follows: First, the road bears a large amount of traffic every day. Under the action of wheel load, when the tensile stress generated at the bottom of the pavement structure layer is greater than the tensile strength of its material, the pavement will produce load-type cracks; It is affected by regional rainfall, and the temperature difference between day and night is large. The temperature cracks caused by the temperature change of the asphalt surface layer, including low-te...

AI Technical Summary

Problems solved by technology

[0003] Asphalt pavement cracking not only destroys the continuity, integrity and aesthetics of the pavement, but also seriously affects the service life of the pavement. If effective measures are not taken in time for maintenance and repair, it will cause damage to a larger area of ​​the road. The existing domestic and foreign The crack treatment method is the slotting repair method. First, the slotting machine is used to slot, and then the slot filling machine is used to fill the slots. However, the existing slot filling machines have the following problems: first, the slots are difficult to clean after slotting, and the inside of the slots There are dust and other impurities that are easy to remain in the gaps, which directly affect the effect of joint filling; second, the joint filling machine cannot effectively flatten the filling material after filling the joint; third, the filling material is easily precipitated in the joint filling machine, If it is condensed and solidified, the fluidity of the filler will become poor, and it will not flow out well, which will affect the repair quality
