Description

Technical Field

[0001] The utility model relates to the technical field of road administration equipment, in particular to an asphalt pavement repairing device. Background Art

[0002] Asphalt pavement refers to various types of pavement paved with road asphalt materials mixed into mineral materials. Asphalt pavement is a type of structure widely used in my country's highway engineering. This material type includes asphalt mixture, inorganic binder stabilized mixture and granular material. Asphalt binder improves the ability of paving granular materials to resist damage to the road surface caused by driving and natural factors, making the road surface smooth, dust-free, impermeable and durable. At present, asphalt pavement repair equipment is needed when carrying out road maintenance work on asphalt pavement.

[0003] The utility model with prior art publication number CN216586071 U relates to an asphalt pavement repairing device, wherein a trowel plate can smooth the asphalt during repair so that the repaired pavement is relatively flat, and the smoothed pavement can be compacted by the compacting roller to compact the repaired asphalt, thereby enabling the repairing device to perform smoothing and compacting work, thereby eliminating the need for subsequent repair personnel to smooth the filled repair position, greatly reducing the labor intensity of the repair personnel, simplifying the operation, saving the time required for pavement repair, and achieving the effect of improving the efficiency of pavement repair.

[0004] However, the above-mentioned device still has the following problems when in use: when the existing asphalt pavement repair device is repairing the road surface, although it is equipped with an asphalt mixture stirring mechanism, its asphalt mixture is very easy to cool and solidify, which is not conducive to extraction through a material pump, and often requires a matching heated mixer truck. In addition, most of the existing asphalt pavement repairs use a single pressure roller for compaction, but after a single pressure roller squeezes the damaged asphalt surface once, it is difficult to achieve a good compaction effect.
