Background technique

Asphalt pavement construction generally uses paver to lay asphalt material, and then uses road roller to compact it. During the compaction process, the asphalt material on both sides of the edge will inevitably expand to varying degrees, resulting in uneven edges on both sides of the road surface. For roads, templates will be built on both sides in advance to delineate the paving range of asphalt materials, so as to avoid the above situation. However, during road maintenance or original road reconstruction, due to the small volume involved, templates are generally not rebuilt , but chose to manually remove the excess asphalt material on both sides after paving. Although the goal can be achieved, the efficiency is not optimistic, and it requires a large labor cost.
