Problems solved by technology

However, in this technical solution, the slits are not cut, which makes the pavement repair uneven, thereby affecting the safety of vehicles; at the same time, the repaired pavement is not cleaned, so that the bonding force between the asphalt concrete mixture and the repaired area is poor, Thus affecting the repair effect of the pavement; making the technical solution limited

Embodiment approach

[0058] As an embodiment of the present invention, an activated carbon layer 143 is provided on the inner wall of the filling chamber 14 . The asphalt concrete mixture has an unpleasant smell, which is harmful to the human body. By providing an activated carbon layer 143 in the filler chamber 14, the activated carbon layer 143 absorbs the odor in the asphalt concrete mixture, thereby preventing the odor from causing harm to the human body. hazards, thereby improving the efficiency of pavement repair.

[0059] As an embodiment of the present invention, the filler chambers 14 are distributed at both ends of the locomotive 1 . The two ends of the locomotive 1 are provided with filler chambers 14 to maintain the balance of the locomotive 1, thereby improving the safety of the locomotive 1 in operation.

[0060] During use, the locomotive 1 is driven to the road surface that needs to be repaired, the driving motor 21 is driven, the cam 22 squeezes the No. 1 disk 23, and the No. 1 a...

Abstract

The invention belongs to the technical field of road construction, in particular to a method for repairing damaged asphalt pavement. The method adopts a repairing device which comprises a locomotive and a rolling wheel. The utility model also comprises a No. 1 plate, a driving unit, a cutting unit, a control unit and a No. 1 cleaning unit. The rolling roller is used for tamping the asphalt concrete mixture; The cutting unit is used for slotting the damaged part of the pavement; The No. 1 cleaning unit cleans the slotted road surface. On the one hand, the asphalt concrete mixture is completelypoured into the repairing notch, and the pavement is leveled by the rolling roller, so that the driving safety of the vehicle is improved; on the other hand, the asphalt concrete mixture is completelypoured into the repairing notch by the mutual cooperation of the cutting unit, the cleaning unit No. On the other hand, the dust in the pavement cutting is cleaned out of the notch to increase the bonding force between the asphalt concrete mixture and the notch, thus prolonging the service life of the highway pavement.

Description

technical field [0001] The invention belongs to the technical field of road construction, in particular to a method for repairing damaged asphalt pavement. Background technique [0002] Highway pavement has the advantages of firmness, wear resistance and long service life, but due to long-term overload operation and natural factors, it is likely to be damaged before the maintenance period. This requires timely repairs to the road surface. Existing emergency road repairs are just a layer of asphalt or cement on the damaged road surface, which cannot solve the deeper damage of the road surface. Therefore, soon after the emergency repair, the road surface will still have problems such as cracking and subsidence. However, if the damaged pavement is to be completely repaired, roadbed maintenance must be carried out after the road is closed. The construction period can range from a few weeks to a few months, seriously affecting traffic. At this time, a repair method is needed to...
