Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of road maintenance, and particularly relates to an asphalt pavement edge finishing device. BACKGROUND

[0002] Generally, an asphalt paver is used to lay asphalt material, and then a road roller is used to compact the asphalt material. During the compaction process, the asphalt material on the two sides of the road will inevitably expand to some extent, resulting in uneven edges of the road. Generally, when a new road is constructed, a template is built on both sides in advance to define the paving range of the asphalt material, so as to avoid the above-mentioned situation. However, when a road is repaired or an existing road is reconstructed, the volume involved is relatively small, so a template is generally not re-built, but the excess asphalt material on both sides is manually removed after paving. Although this method can achieve the purpose, the efficiency is not optimistic, and a large amount of labor cost is required. SUMMARY
